Abstract:
In this paper, the LDPC codes used in DVB-S2 and WiMAX are analyzed. A universal structure based on cyclic shift matrices is presented for these codes. A partially parallel decoder is designed with a universal storage resource reusing architecture and serial operation processors. This decoder has been implemented on an Altera EP2S60 platform, and can work for 8 064 bit code length at rates 7/8, 6/8, 5/8, 4/8 and 3/8. Test results show that its code throughput can approach 80 Mbit/s.
Key words: low density parity check (LDPC) codes, decoder, cyclic shift matrices
