This paper presents a programmable semi-parallel architecture for low-density parity-check (LDPC) codes. Communication conflicts are avoided by edge-coloring the code graph and grouping of edges/physical connections by color. The architecture model is easily scalable and programmable for larger block sizes. Though the communication hardware cost is high,(More)
In this paper a modified bit-filling algorithm is used for constructing column-weight two quasi-cyclic low-density parity-check codes with large girths. Code rows are divided into groups. A column is connected to two rows from different groups, which are apart by at least a specified minimum length. Rows that meet the minimum length are searched(More)
