摘要
Abstract
In allusion to the problem of requiring training sequence or channel coefficients being constant in the frame for traditional SNR estimating,the paper proposes a blind SNR estimation algorithm for 8PSK signal in fading channel.The algorithm theoretically analyzes the relation between the SNR and receiving signal,and deduces its analytic expression by polynomial fitting and middle observation value normalizing based on the Statistical properties of the channel.The numerical simulation indicates that the algorithm can achieve perfect SNR estimation effect for the SNR between 0 to 8dB.关键词
