An Internally Adaptive LDPC Coded Ultra Wideband-Impulse Radio System

摘要：

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 multipath channel proposed in the IEEE802.15.3a standard, and the Selective-RAKE receiver with maximal radio combining is used. Simulation result shows that the proposed IALC-UWB-IR system significantly outperforms the conventional UWB-IR systems.
