DS-UWB系统中基于线性预测的盲多用户检测

doi:10.3969/j.issn.1001-2400.2010.04.012

Abstract

Abstract:

A blind multi-user detection algorithm based on linear prediction is proposed for the direct sequence ultra-wideband (DS-UWB) system to provide resistance to multiple access interference (MAI) and inter symbol interference (ISI). The algorithm first applies linear transformation and linear prediction on the received data, in order to suppress MAI, and then estimate and equalize the channel by Singular Value Decomposition (SVD) of the prediction error correlation matrix. According to the simulation results with the IEEE 802.15.3a UWB channel model, the proposed algorithm exhibits reasonably good performance and near-far resistance in multiuser environment compared with the conventional Rake receiver and blind MMSE receiver.

Key words: ultra-wideband (UWB), linear prediction, blind multi-user detection, channel estimation
