摘要

本文提出了一种内部自适应LDPC编码超宽带脉冲无线电(IALC-UWB-IR)系统，该系统能够自适应地选择LDPC码的码率和脉冲重复数。在IEEE 802.15.3a标准中提出的UWB多部分信道下对系统性能进行了评估，并使用了最大无线电组合的选择性rake接收机。仿真结果表明，所提出的1ALC-UWB-IR系统明显优于传统的UWB-1R系统。

An Internally Adaptive LDPC Coded Ultra Wideband-Impulse Radio System

In this paper, we propose an internally adaptive LDPC coded ultra wideband-impulse radio (IALC-UWB-IR) system which is able to adaptively select the code rate of the LDPC code and the number of pulse repetitions. Performance of the proposed system is evaluated under the UWB multipart channel proposed in the IEEE 802.15.3a standard, and the selective-RAKE receiver with maximal radio combining is used. Simulation result shows that the proposed 1ALC-UWB-IR system significantly outperforms the conventional UWB-1R systems.
