Iterative EM receiver for space-time coded systems in MIMO frequency-selective fading channels with channel gain and order estimation.

Iterative EM receiver for space-time coded systems in MIMO frequency-selective fading channels with channel gain and order estimation.

An iterative receiver for a space-time trellis coded system in frequency-selective fading channel is proposed. It performs channel gain estimation and sequence detection by using the expectation-maximization (EM) algorithm. Channel order estimation is included in the receiver to avoid unnecessary tr...
