【摘要】 本文提出一种用于频率选择性瑞利衰落同步ＣＤＭＡ信道的空—时多用户检测方法。该方法将多用户检测和阵列信号处理相结合，较好地克服了影响ＤＳ／ＣＤＭＡ通信质量和用户容量的多址干扰（ＭＡＩ）、多径传播及信道衷减。仿真结果表明该方法具有较好的用户检测性能。更多还原

【Abstract】 This paper proposes an Space-Time Multiuser Detector for frequency-selective rayleigh fading synchronous CDMA channels. The detector combines the multiuser detector with array-processing, and alleviates the effects of multiple-access interference. multipath propagation and fading. Theoretical analysis and simulation show that the detector has good multiuser detecting performance.更多还原
