  • Abstract:
  • To decode the capacity of polar codes we use two most popular soft-output BP algorithms. They are flooding belief propagation (FO-BP) algorithm and soft cancelation (SCAN) algorithm. The flooding belief propagation algorithm produces high signal to noise ratio and cost is also very high. Coming to the soft-output BP algorithm, it produces better result compared to the flooding belief propagation algorithm. Now in this paper, a proposed version of the BP algorithm is given as reduced complexity soft cancelation algorithm (RCSC). Compared to the SCAN the reduced complexity soft cancelation algorithm reduces the number of memory entries by 50%. we can observe that when signal to noise ratio is increased then the error performance improvement of the RCSC becomes more significant. To reduce the decoding latency and to increase the throughput of the RCSC algorithm we proposed a reduced latency soft cancelation (RLSC). At last the both RCSC and RLSC are used in optimized VLSI architectures.
