摘要: In this work, a (576,288) LDPC decoder for 802.16e standard is presented. This design is a partially parallel architecture based on a new optimally reordered decoding scheme. Besides, the proposed architecture handles two different code words at a time to achieve 100% utilization rate of both CNU and BNU. As a result, high throughput and low hardware complexity are achieved. In chip implementation, the proposed design achieves a data rate of 1.45Gb/s with 10 iterations and 7 quantization bits, at the cost of 881K gates, based on UMC 0.18 mu m process technology.
