摘　　要：Dear editor,Polar codes,along with a low complexity successive cancellation(SC)decoding,were discovered in[1]by Ar?kan.It is shown in[2]that the bit errors with the SC decoding are correlated.To improve the performance,other decoding techniques[3,4]and concatenation schemes[5,6]were studied.In this study,the theoretical aspects of the error correlation are investigated to improve the decoding performance of polar codes.This is the first attempt to utilize the error correlation to improve the performance of polar codes.
