Binary Demodulation in Rayleigh Fading With Noisy Channel Estimates - Detector Structures and Performance

In previous work, the authors studied the structure and performance of optimum maximum-likelihood receivers for binary antipodal and orthogonal signals in the presence of Gaussian-distributed channel estimation error and additive white Gaussian noise for flat Rayleigh fading channels. In this paper, they investigate the structure and performance of these receivers for an application where Gaussian-distributed channel estimation error arises: minimum mean-square error channel estimation in quasistatic Rayleigh fading channels. Exact closed-form analytical expressions are derived for the average Bit Error Probability (BEP).
