A Low Complexity Blind SNR Estimator in Mobile Communication
一种移动通信中的低复杂度盲信噪比估计算法

SNRE (Signal-to-Noise Ration Estimator) can be used in a lot of areas in mobile communication, such as the decoder of LDPC code which need it to compute the "a priori" information of received bits. In this paper, a low complexity blind SNRE, FBSNRE (Fading channel Blind SNRE), based on the online estimator in AWGN channel, is presented. Simulation results prove that FBSNRE cam achieve excellent performance when it is applied in the decoder of LDPC code.
