Web4FSK performances at 2500 bps For the QAM modulation, the roll-off factor α varies between 0 and 1. The modulation is tested at each rate for several chosen α values. For example, using a 4QAM... WebWhen the data bit is 0, output frequency is f0. Output frequency becomes f1 when the data bit is 1. The difference between f0 and f1 is the so-called ... 4FSK modulation baud rate = 125 kSps Gaussian pulse-shaping filter, BT = 0.4 FSK frequency deviation = 17 kHz and 51 kHz Over-sampling factor = 10x

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. oranger concealer
