Capacity-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...
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 کاملPartitioned Successive-Cancellation Flip Decoding of Polar Codes
Polar codes are a class of channel capacity achieving codes that has been selected for the next generation of wireless communication standards. Successive-cancellation (SC) is the first proposed decoding algorithm, suffering from mediocre errorcorrection performance at moderate code length. In order to improve the error-correction performance of SC, two approaches are available: (i) SC-List dec...
متن کاملLow Complexity List Decoding for Polar Codes with Multiple CRC Codes
Polar codes are the first family of error correcting codes that provably achieve the capacity of symmetric binary-input discrete memoryless channels with low complexity. Since the development of polar codes, there have been many studies to improve their finite-length performance. As a result, polar codes are now adopted as a channel code for the control channel of 5G new radio of the 3rd genera...
متن کاملOn 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...
