Abstract or Summary
  • Nowadays, error correction codes have become an integral part in almost all the modern digital communication and storage systems. With the continuously increasing demands for higher speed and lower power communication systems, efficient VLSI implementations of those error correction codes have great importance for practical applications. In this thesis, several VLSI design issues for Viterbi decoder and Low-Density Parity-Check (LDPC) codes decoder will be discussed. We propose a low-power memory-efficient Viterbi decoder to reduce the memory read operations in the survivor memory unit (SMU) and the memory size of SMU. We develop a parallel Viterbi decoder for high throughput applications. We also propose an efficient early stopping scheme to reduce the number of decoding iterations for LDPC codes decoding.
