Block sequential decoding of polar codes
Grigorii Trofimiuk, Peter Trifonov · 2015
The problem of efficient decoding of polar codes is considered. A modification of the sequential decoding algorithm is proposed. Instead of processing one symbol at each iteration, we perform ML decoding of blocks of symbols using the tree-trellis list Viterbi algorithm. Numeric results show that the proposed approach significantly reduces the average complexity and latency of the sequential decoder without any performance degradation.
