摘要 本文提出了一个时空域联合处理技术来对抗码分多址通信系统中的多址干扰 .它由智能天线和多用户联合检测结合而成 ,智能天线可以压制与有用信号来向不同的干扰 ,余下的与用户信号来向相同的干扰可以被多用户联合检测系统消除 .这种结构在干扰严重的信道仍能得到令人满意的效果 . A temporal spatial joint processing technique to cancel cochannel interference is proposed in this paper.The inertference with direction apart from the user is suppressed by smart antenna,and the resident interference can be cancelled by a multiuser detection system.In a heavy interference channel,the proposed system can achieve better performance.
