Abstract
Systems, methods, and apparatus are provided for increasing decoding throughput in an LDPC decoder, such as in a wireless communications receiver or in a data retrieval unit. A checker-board parity check matrix and edge-based LDPC decoder structure are provided in which both vertical and horizontal processors are used simultaneously. Horizontal processors may be grouped into type-A and type-B horizontal processors, and similarly, vertical processors may be grouped into type-A and type-B vertical processors. Type-A processors may be used in different clock cycles than type-B processors to update memory locations in a decoding matrix without causing memory access conflicts.
