短波信道FH／DQPSK系统比特误码率的实时监测
Real-time monitoring channel's bit-error-rate in short wave for FH／DQPSK system
摘要
Abstract
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.关键词
