Abstract :
Spatial-temporal processing is an effective technique for wireless systems with antenna arrays to improve the quality and capacity of communications. Spatial temporal receive filters and equalizers for multiple receiver systems with intersymbol interference (ISI), cochannel interference (CCI), and additive white Gaussian noise (AWGN) are investigated. An analogical spatial-temporal matched filter that is optimum for any following T-spaced processor with any reasonable criterion of goodness is found. Therefore, it allows cochannel interference suppression and equalization to be treated separately. Then, we demonstrate the application of spatial-temporal processing in the IS-136 TDMA and the EDGE systems by two simulation examples
