Abstract

In this paper, we consider a layered decoding algorithm for a performance improvement of LDPC. The proposed algorithm is based on a serial scheduling algorithm for the layered decoding of LDPC in which we consider check node degree, variable node degree, and the edge connection between the each node. Simulation results show that the proposed method improves about 0.2dB SNR gain compared with random schedule in a layered decoding. Especially when the maximum number of iteration and the code rate are low, the performance gain gets larger. This is desirable to the system which requires low per consumption and low latency such as WPAN system.
