摘要 提出用于CDMA系统上行信道的利用时间转换技术的空—时多用户检测算法,并给出了具有阵列天线的CDMA系统的设计和分析.基于DCMA编码和它们的空间信息,提供了结合阵列形式的WLS多用户检测算法,推导出干扰加噪声率(SINR)和误码率(BER)的计算公式.仿真结果表明,WLS多用户检测器是有效的.有阵列天线的CDMA系统比目前CDMA系统有更高的系统容量和更好的性能. In this paper, we develop a space_time multiuser detection approach to uplink channels of CDMA systems with time_switching technique. The design and analysis of the CDMA systems with array antennas are presented. Based on CDMA codes and their spatial information, the WLS multiuser detection algorithm combined the array pattern is provided. The calculation formulas for interference plus noise ratio(SINR) and bit error rate(BER) have been derived. Simulations show that the WLS multiuser deterctor is effective, and the CDMA systems with array antennas can get higher system capacity and can be of better performance than the presented CDMA systems.
