A NEW METHOD OF PILOT-SYMBOL-AIDED CHANNEL FADING ESTIMATION
一种新的导频符号辅助下的信道衰落估计方法

A new method of pilot-symbol-aided(PSA) channel fading estimation is proposed, which uses the data symbols and the pilot symbols to perform channel fading estimation and fading compensation, but normally only pilot symbols are used to estimate the signal distortion. The technique has the advantages of simple implementation and short delay time. The simulation based on 16PSK and 16QAM shows the performance of PSA-16QAM is better than that of PSA-16PSK, and the use of PSA technique can improve the performance relative to the differential detection.
