摘要

本文针对WiMAX标准，提出了一种采用并行窗增强Max-log-MAP解码的高吞吐量12模卷积turbo解码器。为满足多路传输，实现了10个并行窗解码和基本并行窗设计，具有高效的可重构性和无内存冲突的特点。采用台积电0.13 μ m CMOS工艺实现后，所提出的wimax兼容12模CTC解码器的硅面积为5.21 mm2，最大吞吐率为115.4 Mbps。

High-throughput 12-mode CTC decoder for WiMAX standard

In this paper, the high-throughput 12-mode convolutional turbo decoder which employs the parallel-window enhanced Max-log-MAP decoding is presented for WiMAX standard. To satisfy the multiple transmissions, 10 parallel windows decoding and the basic parallel-window designs are realized to have the features of efficient reconfigurability and no memory collision. After the implementation using the TSMC 0.13 mum CMOS process, the proposed WiMAX-compliant 12-mode CTC decoder occupies silicon area of 5.21 mm2 and achieves the maximum throughput rate of 115.4 Mbps.
