摘要

本文研究了将最小均方误差线性空时处理串联逐次干扰消除(MMSE-SIC)应用于重载环境下RRCOS脉冲整形(35% ~ 75% rollloff)符号异步/spl pi//4-DQPSK信号的提取。通过仿真分析了按取消顺序排列的码元错误率的性能。考虑了信号过量带宽、相邻信道干扰、用户数量、信噪比和阵列类型等因素的影响。假设所有用户的通道统计信息是已知的。

Overloaded array processing with MMSE-SIC

This paper considers the application of minimum mean squared error linear space-time processing in tandem with successive interference cancellation (MMSE-SIC) to the extraction of symbol-asynchronous /spl pi//4-DQPSK signals with RRCOS pulse shaping (35%-75% rolloff) in overloaded environments. The performance is analyzed through simulation in terms of the symbol error rate ranked by cancellation order. The effect of signal excess-bandwidth, adjacent channel interference, the number of users, SNR, and array type are considered. The channel statistics of all users are assumed known.
