摘要：
In this paper, the application of Space Time Adaptive Processing (STAP) to Direct Sequence Code Division Multiple Access (DS-CDMA) Ultra Wideband (UWB) multiuser systems for perfect equalization and Multi Access Interference (MAI) suppression is developed. In a single antenna system, the adaptive Minimum Mean Square Error (MMSE) receivers for DS-CDMA UWB systems are able to gather multipath energy and reject intersymbol interference (ISI) & interchip interference (ICI) to a much greater extent. Multi access interference (MAI) is suppressed to a certain extent using adaptive MMSE receivers. STAP processing has been proven to be an effective method for perfect equalization and interference suppression. The proposed STAP receiver for DS-CDMA UWB system preserves the desired array gain and robust to MAL Simulation results show that the performance of the UWB STAP receiver is better than the single antenna adaptive MMSE receiver in multiuser and multipath environments.
