Real-time monitoring channel's bit-error-rate in short wave for FH/DQPSK system

It analyzed the symbol-error rate(SER) and pseudo-error rate(PER) of DQPSK modulated signal in the SW/FH system with Rayleigh fading channel based on the modulation/demodulation technique in Short-wave FH/DQPSK system. According to the theoretical analyzed and numerical simulated results, it obtains the approximately linear relationship between PER and SER, and presents a real-time monitoring estimating method of BER. This method is to estimate BER according to pseudo-error monitoring statistic. The theoretical analyzed and numerical simulated results showed that the relative error (56.4%) by using this monitoring estimating method in FH/DQPSK system is superior to that (79%) in FH/DQPSK system.
