Abstract :
This paper presents a hardware design of a LDPC decoder where Min-Sum (MS) and Modified Min-Sum (MMS) algorithm has been investigated. The parity check matrix is complied with IEEE 802.11n recommendation (code rate of 0.5, 648 bits block length). Verilog description language is employed for Xilinx XC2VP30-7 FPGA. With the matrix reordering technique, the final design shows that the data rate of 127 Mbps could be achieved when the pipeline stages are used.
