In this paper, the use of Smart Antenna with multiple directional beams employed at base station in a Time Division Synchronous Code Division Multiple Access (TDSCDMA) system standard is studied. To improve spatial resolution of the Antenna to BTS Link and BTS to Antenna link of the TD-SCDMA base stations, the proposed Adaptive capability of Smart antenna is tested. The time-varying weight coefficients along with the Matched Filter correlator and joint detection technique employedin the downlink beamformer are estimated by the feedback data from its uplink of the TD-SCDMA system. We present a physical layer design of TDSCDMA including the performance analysis for the 3G TD-SCDMA network with smart beamforming at the base station for both uplink & downlink & the results show that the implementation of the smart antenna for TD-SCDMA systems can improve the performance of the system capacity several fold.
