On Path Memory in List Successive Cancellation Decoder of Polar Codes
Polar code is a breakthrough in coding theory. Using list successive cancellation decoding with large list size L, polar codes can achieve excellent error correction performance. The L partial decoded vectors are stored in the path memory and updated according to the results of list management. In the stateof-the-art designs, the memories are implemented with registers and a large crossbar is u...
متن کاملHardware Implementation of Successive-Cancellation Decoders for Polar Codes
The recently-discovered polar codes are seen as a major breakthrough in coding theory; they provably achieve the theoretical capacity of discrete memoryless channels using the low complexity successive cancellation (SC) decoding algorithm. Motivated by recent developments in polar coding theory, we propose a family of efficient hardware implementations for SC polar decoders. We show that such d...
متن کاملChannel capacity of polar coding with a given polar mismatched successive cancellation decoder
Arıkan’s polar coding, is by now a well studied technique that allows achieving the symmetric capacity of binary input memoryless channels with low complexity encoding and decoding, provided that the polar decoding architecture is used and the decoding metric is matched to the true channel. In this paper, we analyze communication rates that are achievable when the polar coding/decoding architec...
متن کاملStudy on Successive Cancellation Decoding of Polar Codes
Thanks to the property of provably capacityachieving, the recently-discovered polar codes are being taken many attentions. The Successive Cancellation (SC) is the first and widely known decoding for polar codes. In the paper, we study the decoding beginning with its recursive formula. Compared with previous works, our study is more strict and many fresh results are presented which would be help...
متن کاملCapacity-Achievability of Polar Codes under Successive Cancellation List Decoding
Polar codes under successive cancellation decoding proposed by Ar{\i}kan provably achieve the symmetric capacity of any given binary-input discrete memoryless channel. The successive cancellation list decoder for polar codes was described by Tal and Vardy as a generalization of the successive cancellation decoder of Ar{\i}kan. The performance of the successive cancellation list decoder is encou...
