Multiuser Detection for Mobile Communication Signals in Urban Architecture

Abstract

Aim to the problem of code-division multiple-access (CDMA) with both multiple-access interference (MAI) and intersymbol interference (ISI) in dispersive channels of cellular mobile communication under urban architecture’s influence, low-complexity multiuser detection is proposed to suppress MAI and ISI jointly. This technique is considered to base on a blind linear filter detector with the subspace-based and auxiliary vector incorporated the desired user's signature waveform. It is showed that the performance of newly proposed detector outperforms the conventional detectors.
