MEMORY UTILIZATION METHOD FOR LOW DENSITY PARITY CHECK CODE, LOW DENSITY PARITY CHECK CODE DECODING METHOD AND DECODING APPARATUS THEREOF

摘要

A memory utilization method of low density parity check code (LDPC), a LDPC decoding method and a decoding apparatus thereof are provided, applicable for a decoding process in a wireless receiver. The memory utilization method of LDPC includes the following steps. First, variable node processes (VNPs) or check node processes (CNPs) required to be executed at a same time stage are determined. Next, the VNPs or the CNPs executed at the same time stage are allocated in different VNP groups or different CNP groups. Further, a folding factor of memory units is determined according to a desired data throughput. Then, according to the folding factor and the allocated VNP groups or the allocated CNP groups, the memory units are connected serially as a plurality of parallel processing memory modules.
