摘要
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 provides a 30% hardware area reduction and a 36% power consumption saving with the same error correcting performance.
