| 摘 要： | 在DS/CDMA系统中,多用户检测技术可以减小多址干扰和远近效应,但一般情况下,多用户检测总是假设接收机对信道特性已知。本文提出一种慢衰落信道中的有效的联合信道估计和干扰抵消方法,这种方法需要很少的导频符号来进行信道估计,而且实现简单,可以用在较快衰落信道中。

| Abstract: | Abstrct: Multiuser detection (MUD) is a powerful technique for mitigating the effects of multiple access interference(MAI) and near- far problems in DS/CDMA systems. In this paper, an effective joint channel estimation and data detection method with differential modulation and interference cancellation over slow varying fading channels is presented. With this method, near one- user performance with few pilots can be achieved. Furthermore, the receiver is near- far resistant and complexity of the scheme is quite small and can be reliably used in relatively fast fading channels. |
