A New Rate Compatible MET-LDPC Code
You Yin · Journal of Xiamen University of Technology · 2013
In order to increase the throughput, the wireless communication system needs to be adaptive in adjusting the rate and code length of error correction codes according to channel conditions. A hierarchical extended algorithm based on the multi-edge structure of the Multi- Edge Type Low Density Parity Check is proposed to obtain the rate compatible MET-LDPC code over a code rate range from 0. 2 to 0. 5. Simulation over AWGN channels show that the proposed RC-Met-LDPC code has superior performance on frame error rate and throughput in the HARQ communication system.
