| 摘 要： | 在TD-SCDMA系统,已提出的多小区联合检测和消除相邻小区干扰来抑制小区间干扰的方法都只考虑了单小区联合信道估计,不能提供对每个小区足够大的信道估计精确度,尤其是当来自其它小区的干扰非常大时.现提出了一种多小区联合检测方法,可以同时精确地估计当前小区和相邻小区的信道冲击响应.仿真结果表明:该方法对所有考虑到的小区都可以大幅度提高信道估计精确度,多小区联合检测的系统性能也明显得到了提高.

| Abstract: | In the TD-SCDMA system,multi-cell joint detection and adjacent cell interference cancellation technology have been proposed to suppress the inter-cell interference.However,the current technology only takes into consideration a single cell joint channel estimation,which does not provide enough accuracy for channel estimation,especially when the interference from other cell is very strong.A multi-cell joint detection method,which can estimate the channel impulse response with high precision,is presented in th... |
