Electrical Engineering
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control, and electrical m ...

Orthogonal Time Frequency And Space
Orthogonal Time Frequency Space (OTFS) is a 2D modulation technique that transforms the information carried in the Delay-Doppler coordinate system. The information is transformed in the similar time-frequency domain as utilized by the traditional schemes of modulation such as TDMA, CDMA, and OFDM. It was first used for fixed wireless, and is now a contending waveform for 6G technology due to its robustness in high-speed vehicular scenarios. OTFS is intimately related to an earlier modulation 2D modulation scheme - called orthogonal short-time Fourier (OSTF) signaling - and is related to it through a 2D discrete Fourier transform. In this regard, OTFS is simply a precoded version of OSTF. Yet, OSTF defines the critical analog-digital interface that is matched to the characteristics of the time-varying wireless channel. __TOC__ Overview OTFS is a modulation scheme where each transmitted symbol experiences a near-constant channel gain even in channels at high carrier frequenci ...

He is known for developing Orthogonal Time Frequency and Space (OTFS) modulating techniques, a method used for making wireless 5G communications faster, that is also being considered for use in 6G technology. The technology is being used by several wireless 5G related companies and Cohere Technologies, a company he has co-founded. Early life and education Hadani received his MS degree in Computer Science from the Weizmann Institute of Science in 1999 under the supervision of David Harel.

Terayon
Terayon Communication Systems, Inc. was a company that vended equipment to broadband service providers for delivering broadband voice, video and data services to residential and business subscribers. History Terayon was founded by Israeli brothers Zaki Rakib and Shlomo Rakib in 1993; both brothers graduated from high school at age 16 and went on to university. Shlomo studied electrical engineering, and Zaki did a PhD in mechanical engineering and post-doctorate studies in applied mathematics. He taught for a while at Tel Aviv University’s computer science faculty, and then joined Helios. After Helios was sold to Cadence Design Systems, Zaki moved to the US, and urged his brother to join him and set up the company. Terayon held an IPO on NASDAQ in August 1998. In 1999, the company initiated a strategy to expand its offerings to the telecommunication and satellite industries but later refocused its business on the cable industry in 2000. During 1999 and 2000 the company acquired ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Israeli Navy
The Israeli Navy ( he, חיל הים הישראלי, ''Ḥeil HaYam HaYisraeli'' (English: The Israeli Sea Corps); ar, البحرية الإسرائيلية) is the naval warfare service arm of the Israel Defense Forces, operating primarily in the Mediterranean Sea theater as well as the Gulf of Eilat and the Red Sea theater. The current commander in chief of the Israeli Navy is Aluf David Sa'ar Salama. The Israeli Navy is believed to be responsible for maintaining Israel's offshore nuclear second strike capability. History The origins of the Israeli Navy lay in the founding of the Betar Naval Academy, a Jewish naval training school established in Civitavecchia, Italy, in 1934 by the Revisionist Zionist movement under the direction of Ze'ev Jabotinsky, The Academy trained cadets from all over Europe, Palestine and South Africa and produced some of the future commanders of the Israeli Navy. In September 1937, the training ship ''Sarah I'' visited Haifa and Tel Aviv as part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Code-division Multiple Access
Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this without undue interference between the users, CDMA employs spread spectrum technology and a special coding scheme (where each transmitter is assigned a code). CDMA optimizes the use of available bandwidth as it transmits over the entire frequency range and does not limit the user's frequency range. It is used as the access method in many mobile phone standards. IS-95, also called "cdmaOne", and its 3G evolution CDMA2000, are often simply referred to as "CDMA", but UMTS, the 3G standard used by GSM carriers, also uses "wideband CDMA", or W-CDMA, as well as TD-CDMA and TD-SCDMA, as its radio technologies. It can be also used as a channel or m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DOCSIS
Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable television (CATV) system. It is used by many cable television operators to provide cable Internet access over their existing hybrid fiber-coaxial (HFC) infrastructure. History DOCSIS was originally developed by CableLabs and contributing companies, including Arris, BigBand Networks, Broadcom, Cisco, Comcast, Conexant, Correlant, Cox, Harmonic, Intel, Motorola, Netgear, Terayon, Time Warner Cable, and Texas Instruments. Versions ; : Released in March 1997, DOCSIS 1.0 included functional elements from preceding proprietary cable modems. ; : Released in April 1999, DOCSIS 1.1 standardized quality of service (QoS) mechanisms that were outlined in DOCSIS 1.0. ; (abbreviated D2) : Released in December 2001, DOCSIS 2.0 enhanced upstream data rates in response to increased demand for symmetric s ...

Cable Modem
A cable modem is a type of network bridge that provides bi-directional data communication via radio frequency channels on a hybrid fibre-coaxial (HFC), radio frequency over glass (RFoG) and coaxial cable infrastructure. Cable modems are primarily used to deliver broadband Internet access in the form of cable Internet, taking advantage of the high bandwidth of a HFC and RFoG network. They are commonly deployed in the Americas, Asia, Australia, and Europe. History MITRE Cablenet Internet Experiment Note (IEN) 96IEN 96 - The Cablenet Project (1979) describes an early RF cable modem system. From pages 2 and 3 of IEN 96: The ... |
Asynchronous Transfer Mode
Asynchronous Transfer Mode (ATM) is a telecommunications standard defined by American National Standards Institute (ANSI) and ITU-T (formerly CCITT) for digital transmission of multiple types of traffic. ATM was developed to meet the needs of the Broadband Integrated Services Digital Network as defined in the late 1980s, and designed to integrate telecommunication networks. It can handle both traditional high-throughput data traffic and real-time, low-latency content such as telephony (voice) and video.ATM Forum, The User Network Interface (UNI), v. 3.1, , Prentice Hall PTR, 1995, page 2. ATM provides functionality that uses features of circuit switching and packet switching networks by using asynchronous time-division multiplexing.McDysan (1999), p. 287. In the OSI reference model data link layer (layer 2), the basic transfer units are called '' frames''. In ATM these frames are of a fixed length (53 octets) called ''cells''. This differs from approaches such as Internet Pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
