摘要：
This paper presents a novel iterative receiver for mobile handsets using multiple antennas in the GSM/EDGE system. The receiver is derived based on the space alternating-generalized expectation-maximization (SAGE) method. It performs joint channel estimation, spatial diversity combining and successive co-channel interference (CCI) cancellation. The channel impulse response of all users are jointly estimated, while the users' transmitted symbols are detected successively. The receiver has a tractable complexity that increases linearly with the number of interferers. Two practically relevant applications are investigated by means of Monte Carlo simulations: single antenna interference cancellation (SAIC) in the GSM system and dual antenna interference cancellation (DAIC) in the EDGE system. Simulations using the TU3 channel model show that the new proposed scheme achieves a significant performance gain compared to the conventional receiver at low signal-to-interference ratios (SIRs).
