A 179-mW 2304-bit flezible LDPC decoder for Wireless-MAN Applications

摘要：

A 2304-bit flexible decoder for low-density parity-check (LDPC) codes is presented for Wireless-MAN applications. Based on modified turbo-decoding message-passing (M-TDMP) algorithm,the decoder achieves low complexity as well as fast convergence which produces high throughput of 138Mbps working at 50MHz. By adopting a novel scheme for early termination of iteration,the proposed decoder obtains large power efficiency. The decoder is implemented in SMC 0.18um 1P6M CMOS technology,features a power dissipation of 179-mW operating at 50MHz,and costs an area of 12.5 mm2.
