摘要

本文着重分析一种新的盲多用户检测器(即常数模检测器)的多址干扰抑制能力.所得到的结果是:当解调信号的接收幅值小于临界值1/ 3 时

该检测器的性能较差;相反

则具有较强的多址干扰抑制能力.仿真实例验证了这一结论.

Abstract

The paper investigates a new blind multiuser detector called constant modulus detector and analyzes the capability of the detector to suppress multi-access interference (MAI).The results show that the performance of detector is poor when the received amplitude of the demodulated signal is less than the critical value 1/ 3

contrariwise

the detector possesses stronger capability of MAI suppression.The simulation examples demonstrate the results.
