摘要
提出了一种基于边界度量编码的双二进制圆形turbo解码器。该方法将分支存储器的内存大小减少了一半，并且以保留编码边界度量的小内存为代价消除了虚拟计算。基于所提出的SISO解码器和专用硬件交织器，设计了一种适用于WiMAX标准的双二进制圆形turbo解码器，该解码器采用0.13 μ m CMOS工艺，在200 MHz下可支持24.26 Mbps。
Duo-binary circular turbo decoder based on border metric encoding for WiMAX
This paper presents a duo-binary circular turbo decoder based on border metric encoding. With the proposed method, the memory size for branch memory is reduced by half and the dummy calculation is removed at the cost of the small-sized memory which holds the encoded border metrics. Based on the proposed SISO decoder and the dedicated hardware interleaver, a duo-binary circular turbo decoder is designed for the WiMAX standard using a 0.13 mum CMOS process, which can support 24.26 Mbps at 200 MHz.
