| 摘 要： | 使用串行干扰消除(SIC)方法进行MIMO系统信号检测时,先检测出的信号对后续层信号的检测有很大影响,存在误差传播现象.针对这一问题,提出一种改进的SIC检测算法.所提算法在进行SIC检测时,对前层采用穷举搜索,并对所得到的P维信号的累积度量值进行计算和排序,从中取出L组具有最小度量值的信号,再对其后续层利用SIC进行...

| Abstract: | When using successive interference cancellation(SIC) in MIMO detection,overall performance is determined by the first stages being decoded due to error propagation.To solve this problem,an improved SIC detection algorithm was proposed.For the algorithm undergoing SIC detection,an exhaustive search of initial P level signals was conducted,and accumulated metrics were calculated and arranged in order.From these were selected L signals with the smallest metrics. Then SIC algorithms were used to detect ongoing ... |
