MIMO receiver for processing N data streams received by N antennas for a direct-sequence (DS) spread-spectrum wireless communication system comprising: a first linear equalizer operating at the chip level for performing linear chip level Inter-Chip Interference (ICI) and all Inter-Stream Interference (ISI) cancellation (Channel Shortening) of said N data streams, and generating N output chip level data streams; de-spreading blocks for separately de-spreading the N outputs of said first linear equalizer; a second non linear detector for performing spatial equalization and multi-stream detection. The invention also provides a process for processing the mimo data streams based on the separate performing, on one side, of a linear chip level Inter-Chip Interference (ICI) an and all Inter-Stream Interference (ISI) cancellation and, on the other side, spatial multi-stream detection.
