This paper proposes an improved message passing schedule for irregular LDPC decoder. Redundant memory accesses and column operations are removed by utilizing the characteristics of partial-parallel irregular LDPC decoding algorithm. As a result, the memory access frequency and hardware cost are efficiently reduced. According to the experimental results and comparison with existing work, proposed decoder...
In this paper, we propose a new efficient message-passing schedule for irregular LPDC code. Our approach is based on the schedule designed for regular LDPC code. We have modified the original schedule for regular LDPC code and improved it particularly for the irregular LDPC coder realization. The experimental results show that our method could achieve better performance than conventional one, and...
