Polar Codes Applications for 5G Systems

Improving data transmission over wireless channels has been the main obsession for many researchers for years. Since Shannon has discovered his theorem of information transmission, a lot of work has been done to attain his limit nevertheless no one has succeeded. Polar codes are the first provably codes that arrive to near Shannon’s limits of capacity, therefore, they have most of the researchers’ interest to be studied in 5G systems. As 5G systems require significant improvements in channel capacity, polar codes are the promising techniques that have the ability to offer these improvements. In this paper, we focus on studying polar codes in 5G systems. Moreover extracting polar codes in three common channels are studied. These channels are Binary Erasure Channel (BEC), Binary Symmetric Channel (BSC) and Additive White Gaussian Noise (AWGN) channel. Decoding information via polar codes is done by many methods, however, we give details about four common methods which are Successive Cancellation (SC) decoding, Successive Cancellation List (SCL) decoding, Cyclic Redundancy Check -Aided Successive Cancellation List (CRC-SCL) decoding and Adaptive Successive Cancellation List (Adaptive-SCL) decoding. We compare between them according to systems complexity and Block Error Rate (BLER). In this study, we provide details about the trial system of 5G encoder and decoder with polar codes and the general communication system with these codes.
