针对CSMA协议的干扰抵消技术。Successive interference cancellation (SIC) is an effectiveway of multipacket reception to combat interference. As conventional CSMA (Carrier Sense Multiple Access) is designed for single packet reception, it is unclear whether or not
为了进一步提高信号检测的准确度,基于最小均方误差检测算法,提出一种改进的可靠性较高的多输入多输出信号检测算法。改进算法在检测过程中引入排序机制的排序串行干扰抵消算法,优先估计可靠性高的检测分量,结合最大似然检测算法修正可靠性低的分量。结果表明:改进后的检测算法复杂度提升不大,在误码率一定时,信噪比相比与原算法提高了约3 d B;在信噪比一定时,误码率低于原算法,性能得到优化。该研究可以为多输入多输出系统中信号的检测提供参考。
