Comparación de las técnicas de codificación de canal de Quinta Generación NR-LDPC y NR-Polar en un canal AWGN con modulación BPSK y cuantización de punto fijo mediante una simulación en Matlab.

Abstract

One of the characteristics of wireless communications is that the received data differs from the transmitted data due to phenomena/anomalies present in the wireless channel, such as fading, interference and noise, a drawback that can be solved with the implementation of channel codes. In the case of cellular radio communications, the specifications of the fifth generation of cellular radio networks called New Radio (NR) can be found in the specifications of the Third Generation Partnership Project (3GPP). Version 15 of the standard through technical report TS 38.212 defines, based on theoretical and practical studies, two new channel coding schemes: New Radio - Low Density Parity Check Codes (NR-LDPC) and New Radio Polar (NR- Polar). The objective of introducing these schemes is to provide support to the three new fields of application defined in technical report TS 138.912 for New Radio (Enhanced Mobile Broadband -eMBB-, Ultra Reliable Low Latency Communications -URLLC-, Massive Machine Type Communications -mMTC-). This document makes a theoretical compilation and an evaluation of the performance of both coding schemes to analyze their characteristics. The results have concluded that both schemes handle defined characteristics such as the number of iterations for NR-LDPC or the number of lists for NR-Polar to obtain similar performance in terms of erroneous bit rates at a similar coding rate.
