ABSTRACT:
A receiver for use in performing open loop MIMO performs parallel interference cancellation to reduce interference caused by other spatial streams. Residual interference within an interference-cancelled signal is mitigated using MMSE filtering. The receiver processes received signals in multiple iterations. On each successive iteration, an MMSE filter assumes a lower interference power level than a previous iteration.
