Abstract Based on a kind of short-wave FH-DQPSK system demodulating technology of FFT and according to PER estimation in the DQPSK system with Rayleigll fading channel,this paper proposes a method to estimate BER using adaptive linear extrapolation algorithm, and analyses the confidence level about this method.The numerical simulated results show that the performance of this method is superior to the estimating method without using extrapolation algorithm.
