WebWireless communication at sea is an essential way to establish a smart ocean. In the communication system, however, signals are affected by the carrier frequency offset (CFO), which results from the Doppler effect and crystal frequency offset. The offset deteriorates the demodulation performance of the communication system. The conventional Gardner … Web% Samples per symbol % Due to the low symbol rate and 200 KHz frequency offset, a large value of % 200 samples per symbol must be used as a default value with % PCM/PSK/PM modulation. For BPSK and PCM/PM/biphase-L modulation, a % default value of 20 samples per symbol is used (due to medium and high % symbol rates). sps = 20; % Symbol rate …
