Hardware Architecture for List SC Decoding of Polar Codes
We present a hardware architecture and algorithmic improvements for list SC decoding of polar codes. More specifically, we show how to completely avoid copying of the likelihoods, which is algorithmically the most cumbersome part of list SC decoding. The hardware architecture was synthesized for a blocklength of N = 1024 bits and list sizes L = 2, 4 using a UMC 90nm VLSI technology. The resulti...
متن کاملFast Sequential Decoding of Polar Codes
An extension of the stack decoding algorithm for polar codes is presented. The paper introduces a new score function, which enables one to accurately compare paths of different length. This results in significant complexity reduction with respect to the original stack algorithm at the expense of negligible performance loss.
متن کاملDynamic-SCFlip Decoding of Polar Codes
This paper proposes a generalization of the recently introduced Successive Cancellation Flip (SCFlip) decoding of polar codes, characterized by a number of extra decoding attempts, where one or several positions are flipped from the standard Successive Cancellation (SC) decoding. To make such an approach effective, we first introduce the concept of higher-order bit-flips, and propose a new metr...
متن کاملFast-SSC-Flip Decoding of Polar Codes
Polar codes are widely considered as one of the most exciting recent discoveries in channel coding. For short to moderate block lengths, their error-correction performance under list decoding can outperform that of other modern errorcorrecting codes. However, high-speed list-based decoders with moderate complexity are challenging to implement. Successivecancellation (SC)-flip decoding was shown...
