SINR Maximizing Space-Time Filtering for Asynchronous DS-CDMA
Overview Direct Sequence Code Division Multiple Access (DS-CDMA) is a core technology for wireless access that is proposed for future Generation (3G) mobile and personal communication systems. The use of a base-station antenna array is strongly endorsed in these systems, because of its capabilities of filtering out the interference in the space domain. This paper considers space-time one shot single user receivers for DS-CDMA, based on a multiple input single output time invariant linear filter. The optimization of the filter response is performed jointly in the space and time domains yielding maximal signal-to-interference-plus-noise ratio. Using this framework, a Space-Time Noise Whitening Matched Filter (ST-NWMF) for DS-CDMA demodulation is introduced.
