摘要：
This letter considers joint channel estimation and data sequence detection for multipath radio channels with multiple antennas at the transmitter and/or receiver. An iterative space-time receiver based on the expectation-maximization algorithm is proposed. We examine the performance of this receiver on Rayleigh fading channels for transmit diversity and space-time coding methods. Simulation results show that the receiver can often achieve near-coherent performance with modest complexity and using very few pilot symbols.
