Abstract

The single-input multi-output (SIMO) channel model has been widely used In data transmission and diversity reception systems. In this paper, we consider the problem of joint channel estimation and data detection for SIMO systems under fast-fading channels with unknown spatially correlated noise. We propose an iterative receiver based on expectation maximization (EM) algorithm. Bit error rate (BER) performance of the proposed Iterative receiver Is compared with the maximum likelihood (ML) receiver with perfect channel state Information (CSI). The simulation results show that the proposed iterative receiver exhibit near ML performance with a few iterations.
