Blind SNR estimation for OFDM signals in cognitive radio

The traditional blind SNR estimation algorithms had problems of poor performance and high computation complexity for OFDM systems in cognitive radio with low signal to noise ratio(SNR)and multi-path channel conditions,in view of which a novel blind SNR estimation method for orthogonal frequency divi...
