Olivia MFSK
Olivia MFSK is an amateur radioteletype protocol, using multiple frequency-shift keying (MFSK) and designed to work in difficult (low signal-to-noise ratio plus multipath propagation) conditions on shortwave bands. The signal can be accurately received even if the surrounding noise is 10 dB stronger. It is commonly used by amateur radio operators to reliably transmit ASCII characters over noisy channels using the high frequency (3–30 MHz) spectrum. The effective data rate of the Olivia MFSK protocol is 150 characters/minute. Olivia modes are commonly referred to as Olivia ''X'' / ''Y'' (or, alternatively, Olivia ''Y'' / ''X'' ), where ''X'' refers to the number of different audio tones transmitted and ''Y'' refers to the bandwidth in hertz over which these signals are spread. Examples of common Olivia modes are 16/500, 32/1000 and 8/250. History The protocol was developed at the end of 2003 by Pawel Jalocha. The first on-the-air tests were performed by two radio amateur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
