Performance analysis of a smart antenna system utilizing a test-bed implememted on a dsp board

초록

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.
