WebAug 20, 2024 · Raw bit error rates on multipath channels often exceed 10%. For reasonable latency (say 40ms) we need small codewords. Thus to be useful we require a FEC code that works at over 10% raw BER, has 1% output (coded) bit error rate, and a codeword of around 100 bits. WebMaybe I need to summarize a bit, and remove the ambiguities of the argument, as I think what I wrote had a few too many assumptions of argument. and I made a few mistakes , I was a little tired when I wrote , mixing coherent/incoherent spacings etc..(I don't run simulations, I just do the math) . ...

WebThus, the gross bit rate is: R = baud rate x log2S = baud rate x 3.32 log10S . If the baud rate is 4800 and there are two bits per symbol, the number of symbols is 22 = 4. The bit rate is: R = 4800 x 3.32 log(4) = 4800 x 2 = 9600 bits/s . If there’s only one bit per symbol, as is the case with binary NRZ, the bit and baud rates remain the same.

In principle FSK can be implemented by using completely independent free-running oscillators, and switching between them at the beginning of each symbol period. In general, independent oscillators will not be at the same phase and therefore the same amplitude at the switch-over instant, causing sudden discontinuities in the transmitted signal. In practice, many FSK transmitters use only a single oscillator, and the process of switching to …
