摘要

实现了与等效turbo码的编码增益相匹配的1024比特率-1/2低密度奇偶校验(LDPC)码解码器。并行解码器架构支持高达1gb /s的吞吐量，解码算法的收敛转化为极低的切换活动，功耗低于220 mW。

A 220 mW 1 Gb/s 1024-bit rate-1/2 low density parity check code decoder

A 1024 bit rate-1/2 Low Density Parity Check (LDPC) code decoder has been implemented that matches the coding gain of equivalent turbo codes. The parallel decoder architecture supports throughputs up to 1 Gb/s and convergence in the decoding algorithm translates into extremely low switching activity with power dissipation under 220 mW.
