摘要：
Low Density Parity Check Codes (LDPC) is a class of linear block codes best suited for forward error control in communication systems. When compared with other codes, LDPC codes have significant performance gain, which can be turned to an increase of the coverage range or a reduction of transmission power. Hence a convenient and practical receiver can be obtained. The analysis is done in this paper based on the Signal to Noise Ratio and the Bit Error Rate of the decoded output. The comparison of convolutional codes and LDPC codes in WiMedia PHY is performed by considering different code rates and indoor propagation channel models. LDPC codes have a comparatively constant performance under different channel models.
