根据宽带码分多址（ ＷＣＤＭＡ） 系统的特点，提出并分析了一种导频符号辅助干扰删除多用户检测器（ＰＳＡＩＣ），分析结果表明，该方法充分利用了ＷＣＤＭＡ系统中的帧结构，在不增加物理信道的情况下，实现接收信号的相干解调，并与多址干扰删除器相连，可以大大提高系统的性能，增加系统的容量，当干扰删除器的级数为２ 时，其性能有较大的改善，复杂度也不高
According to the characteristics of wideband code division multiple access (WCDMA) system, a pilot symbol assisted interference cancellation multiuser detector (PSAIC) is proposed and analyzed. The analysis results show that this method makes full use of the frame structure in WCDMA system. Without increasing the physical channel, to achieve the coherent demodulation of the received signal, and connected with multiple access interference removers, can greatly improve the performance of the system to increase the system capacity, when the number of interference canceller is 2, its performance Great improvement, complexity is not high
