摘要

提出了一种基于线性分数间隔均衡(LFSE)的自适应消除CDMA系统中多址干扰的方法。仿真结果表明，LFSE比传统的检测器具有显著的增益，消除了在不明确知道干扰扩散序列的情况下的近远问题。此外，LFSE在没有额外复杂性的情况下执行了扩展和多路径(RAKE)组合。

LFSE interference cancellation in CDMA systems

A method based on linear fractional spaced equalization (LFSE) for adaptively cancelling the multiple access interference in CDMA systems is addressed. The simulation results indicate that the LFSE offers significant gains over the conventional detector eliminating the near-far problem without the explicit knowledge of the interfering spreading sequences. Furthermore, it is demonstrated that LFSE performs despreading and multipath (RAKE) combining with no extra complexity.<>
