Performance analysis of a smart antenna system utilizing a test-bed implemented on a DSP board

In this paper, we present a performance analysis of the smart antenna system operating in a wide-band CDMA (Code division multiple access) WLL (Wireless local loop) channel through a test-bed that has been implemented on a DSP (TMS320C6701) board. The test-bed consists of a PC (for generating the RX data), beam-former (i.e., a stand-alone PCB for weight computation), and an interfacing module. The performance improvements compared to a normal base station system consisting of a single antenna are shown in terms the BER (bit error rate) in the wide-band CDMA WLL channel.
