چکیده
Adaptive Reduced Path Successive Cancellation List (ARP-SCL) decoding for polar codes is proposed in this paper. The aim here to reduce the complexity of conventional (SCL) and a previously SCL (RP-SCL) decoders. reduction obtained at low moderate signal noise power ratio (SNR) regions. operation ARP-SCL decoder relied on calculation different optimum pruning parameters according operating SNR, while RP-SCL used single set. Simulation tests are carried out determine both Bit Error Rate (BER) performances comparison with Additive White Gaussian Noise (AWGN) channel two fading models simulating indoor 5G environment using millimeter Wave (mmWave) carrier frequency 28GHz having either 50 or 400 MHz bandwidths used. results revealed that reduced average processed paths up 46.88%. largest reductions case bandwidth high SNR In most test conditions, mentioned achieved without greatly sacrificing required BER.

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 کاملAn Efficient Partial Sums Generator for Constituent Code based Successive Cancellation Decoding of Polar Codes
This paper proposes the architecture of partial sum generator for constituent codes based polar code decoder. Constituent codes based polar code decoder has the advantage of low latency. However, no purposefully designed partial sum generator design exists that can yield desired timing for the decoder. We first derive the mathematical presentation with the partial sums set βc which is correspon...
