摘要

为了满足现代通信系统的高吞吐量和数据处理要求,开发了高效的最大似然解码(MLD) VLSI阵列处理器架构。推导出了具有大约束长度(bbbb8)的1-D和2-D MLD处理器。将基4p处理单元和延迟交换交换交换处理器连接起来,构成流水线式MLD处理器。管道长度可以适应各种应用的时间/面积限制。提出了一种二维MLD阵列处理器。将处理数据模块化,将数据传输嵌入到处理单元中,并派生出固定尺寸的二维MLD阵列,以满足高数据吞吐量的要求

Implementation of array structured maximum likelihood decoders
Efficient VLSI array processor architectures for maximum-likelihood decoding (MLD) have been developed to meet the high throughput and data processing requirements of modern communication systems. Both 1-D and 2-D MLD processors with large constraint length (>8) have been derived. Radix-4p processing elements and delay commutating switching processors for MLD have been concatenated to construct a pipeline MLD processor. The pipeline length can be adapted to meet the time/area constraints for various applications. A 2-D MLD array processor is also presented. Processing data are modulized, data transmission are embedded into processing elements, and a fixed-size 2-D MLD array is derived to meet high-data-throughput requirements.<>
