摘要

本文提出了一种基于支持向量机(SVM)的多用户检测器,该检测器将接收向量分为+1和-1两类来实现检测。与MMSE检测器不同的是,SVM方法可以找到一个最优的超平面来分离训练数据中的+1和-1。仿真结果表明,在瑞利信道下,与最小均方误差(MMSE)检测器相比,该检测器具有较低的误码率。

A multiuser detection method based on support vector machine
In this paper, a multi-user detector based on a Support Vector Machine (SVM) is proposed, which divides the receiving vector into two classes, +1 and -1, to attain detection. Differing from the MMSE detector, the SVM method can find an optimal hyperplane to separate the +1 and -1 from the training data. Simulation results show that under the Rayleigh channel, this detector can achieve a relatively low BER in comparison with the minimum mean square error (MMSE) detector.
