Abstract

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.
