The SNRE (signal-to-noise ratio estimator) can be used in a lot of areas in mobile communication, such as the decoder of channel code which need it to compute the "a priori" information of received bits. In this paper, we present a low complexity blind SNRE, FBSNRE (fading channel blind SNRE), based on the online estimator in the AWGN channel. Simulation results proved that FBSNRE has high accuracy and better performance when it is applied in the decoder of LDPC code.
