چکیده
Estimation of signal to noise ratio for the received signal is an important task in communication systems. In this paper, a novel approach for such estimation that uses zero point autocorrelation of received signal per block and auto crosscorrelation of decision feedback signal in orthogonal frequency division multiplexing (OFDM) system. The performance of the method is verified qualitatively and they show a stable performance when compared with earlier methods when applied under higher modulation schemes.
