Viterbi译码器的幸存路径存储管理

Survivor-path Memory Management in Viterbi Decoder

介绍了Viterbi译码器的各种幸存路径存储管理方法。以3-指针偶回溯法为传统方法的代表,与改进的寄存器交换法进行了详细的对比,给出了两者在存储资源消耗、译码延时、硬件实现复杂度等方面的比较结果。

Several survivor-path memory management methods based on traceback method are introduced and analyzed. Then a modified register exchange method is introduced and compared with traditional traceback methods in memory size, latency and implementational complexity.
