Abstract

Stäng
- This paper proposes a new class of hybrid VLSI architectures for survivor path processing to be used in Viterbi decoders. The architecture combines the benefits of register exchange and trace-forward algorithms, that is, low memory requirement and latency versus implementation efficiency. Based on a structural comparison, it becomes evident that the architecture can be efficiently applied to codes with a larger number of states where usually trace-back-based architectures, which increase latency, are dominant.
