WebApr 7, 2011 · Very simple modulation schemes, e.g. PSK, just encode one bit per symbol, but more sophisticated schemes can encode several bits per symbol, e.g. QPSK encodes 2 bits per symbol. Hence the symbol rate (symbols per second, aka baud) may be less than bit rate (bits per second). Chip rate is a term which is specific to spread spectrum … WebModulation rates simply outline how many bits per symbol per transmission you can achieve. The more bits that can be represented by a symbol, the more data that can be transferred across your network. The result of using higher orders of modulation is a greater return on investment in your network equipment and spectrum.
