摘要 本文分析了在频率选择性信道中基于智能天线阵接收的蜂窝CDMA网络上行链路的性能。分析基于多个小区的异步蜂窝CDMA系统 ,系统采用BPSK调制 ,并采用智能天线阵接收的RAKE合并技术。通过分析最终得到了在该环境下的闭合的CDMA系统误码率公式 ,结果表明基于智能天线阵接收的蜂窝CDMA性能要比不采用的好得多 ,并给出了误码率与系统用户数 ,小区数和衰落模型之间的关系 。 In this paper the performance of uplink in the cellular CDMA network,based on the reception of smart antenna,is analyzed in the frequency selective fading channel.The analysis is under the asynchronous cellular CDMA system of multiple cells,in which BPSK modulation and Rake combination based on smart antenna reception are employed.The closed forms of average error probability are derived in this paper finally.The numerical results show that the performance of cellular CDMA system based on smart antenna is improved greatly;in addition,the final formula describes the inter relations among BER,the user number of system,the number of cells and fading model.
