Combining space division multiple access (SDMA) with
temporal multiple access techniques such as code division
multiple access (CDMA) helps maximize system capacity
without sacrificing bandwidth [1]. However, both forms of
multiple access schemes are interference limited, therefore
using interference suppression techniques can improve system
effectiveness. In this regard, joint domain adaptive processing
that integrates receive beamforming (spatial processing) and
multiuser detection (temporal processing) outperforms all pos-
sible linear processing based on the minimum mean squared
error (MMSE) criterion [2]. Unfortunately, this processor is
