Different Code Rates of LDPC Decoding Based on CMMB Standard
Shuai Liu, Jing He, Xin Yu Xu · Applied Mechanics and Materials · 2013
In this paper, we present different code rates of LDPC decoding on Chinese Mobile Multimedia Broadcasting standard (CMMB). There are two different code rates (0.5 and 0.75) of LDPC in CMMB standard.In this paper, we use LLR-SPA algorithm to decode and make a simulation. Simulation results show that the higher code rate (0.75) of LDPC code in CMMB standard provides a better performance.
