实现Viterbi译码器幸存路径存储及译码输出的一种新方法

Novel Approach to the Survivor Memory and Decode Out in Viterbi Decoder FPGA Designing

提出了一种幸存路径存储及输出的新方法———SMDO法,该方法与传统的寄存器交换法和回索法相比具有存储量小、译码延迟短的特点,并且极适合利用FPGA内置的EAB块实现。

In this paper a novel approach to the survivor memory and decoding out put outSMDO method was presented. Compared with the traditional techniquesregister exchange(RE) and trace back(TB), this method needs smaller memory and shorter decoding delay. It's very suitable for FPGA implementation.
