摘要

本文对超宽带发射参考技术在时分多址方式和传统脉冲对结构下对高数据传输速率造成的符号间干扰模型进行了分析

证明其属于二阶符号间干扰系统

系数由波形相关矩阵决定.在此模型的基础上利用超宽带室内信道慢衰落的特点

给出了一种无重叠导频进行模型系数的估计方法.引入Turbo原理

采用修正的Turbo均衡器对此非线性符号间干扰系统进行均衡.IEEE802.15.3a室内多径信道仿真表明

Turbo均衡在非线性符号间干扰系统下仍然有效.

Abstract

Based on ultra-wideband (UWB) transmitted reference (TR) technology

the interference model is analyzed for time division multiple access (TDMA) systems with conventional pulse pair structure

in which received reference and data received waveforms are both contaminated by inter-pulse interference.The inter-symbol interference model was demonstrated to be a second-order non-linear system and model coefficients are determined by received waveform correlation matrix.A non-overlapped pilot pulses structure was presented to estimate the model coefficients.Modified turbo equalization algorithm is adopted to equalize the second-order non-linear inter-symbol interference (ISI).Simulation result shows that

for the IEEE 802.15.3a’s indoor multipath channel model

the turbo equalization principle is still effective in TR non-linear ISI systems.
