An iterative space-time receiver based on the expectation-maximization algorithm is proposed. We examine the performance of this receiver for transmit diversity and space-time coding methods over Rayleigh fading channels. Simulation results show that the receiver can often achieve near-coherent performance with modest complexity and using very few pilot symbols.}, number={8}, journal={IEEE TRANSACTIONS ON COMMUNICATIONS}, author={Cozzo, C and Hughes, BL}, year={2003}, month={Aug}, pages={1266–1270} }

In certain wireless applications, however, the number of significant multipath components can be small. In this letter, we consider a multipath channel in which the signal propagates from the transmitter to the receiver via L discrete paths which are uniformly distributed about the transmitter and receiver. For this channel, we study the effects of the number of multipath components and antenna array size on the error probability and outage capacity of space diversity systems. We observe that performance is significantly influenced by the presence of a channel with few multipath components.}, number={10}, journal={IEEE TRANSACTIONS ON COMMUNICATIONS}, author={Cozzo, C and Hughes, BL}, year={2003}, month={Oct}, pages={1629–1632} }

Results suggest that the new receiver can outperform iterative approaches based on Kalman filtering and the expectation-maximization algorithm, at the cost of increased receiver complexity.}, number={8}, journal={IEEE TRANSACTIONS ON COMMUNICATIONS}, author={Cozzo, C and Hughes, BL}, year={2002}, month={Aug}, pages={1213–1216} }
