In this paper, we present a framework for the design of space-time
equalizers that perform joint interference cancellation and channel
shortening in multi-user multiple-input multiple-output
The space-time filter coefficients and the shortened channel vectors
are jointly optimized to minimize the interference-plus-noise using
The receiver design is completed by using an appropriate Viterbi
equalizer in the second stage for inter-symbol interference equalization.
The design is adapted to two different detection schemes: independent
detection and ordered successive interference cancellation.
Simulation results show acceptable symbol error performance with
both detection schemes.
