A spatiotemporal combiner for CDMA receiver using antenna arrays

Considering wireless CDMA communication system over a multipath fading channel, spatiotemporal processing at the receiver seems quite beneficial because as it can alleviate fading effects and suppress interference over the space and time domains simultaneously. This paper discusses efficient techniques for obtaining the beamformer weights in a recursive manner while maximizing SINR (signal to interferences plus noise). To show the superiority of the proposed composite processing for the spatiotemporal combiner, the BER and the SINR curves will be shown under the various environments
