Abstract :
This paper considers joint channel estimation and data detection for multipath radio channels with multiple antennas at the transmitter and/or receiver. An iterative space-time receiver based on the expectation maximization (EM) algorithm is described and performance is investigated on fast fading channels for several transmit diversity and space-time coding schemes
