FER Polar Codes Performances Using 5G Broadband Channel with CP-OFDM Techniques at 2.3 GHz Frequency

The use of high frequencies in the 5G system resulting in the sensitivity of the surrounding environment and attenuation such as human blockage. This study analyzed the performance of frame error rate (FER) based on polar code and without polar code on broadband channels that are affected by human blockage using a frequency of 2.3 GHz, bandwidth of 99 MHz, and the CP-OFDM technique. The purpose of this research is to determine the FER performances using polar codes and without polar codes on 5G network broadband channels that are affected by human blockage which has been validated with outage performances. Broadband channels on the 5G network are presented in a representative Power Delay Profile (PDP) with the influence of human blockage obtained as many as 41 paths with multiple delays of 10 ns on each path. This research was also used the scaling method on representative PDP because it could adjust the use of FFT of 128 blocks and the results of this scaling showed that there are 9 paths with multiple delays of 50 ns. This research evaluates the average FER of 10-3. FER performance without a polar code is affected by human blockage (R=1) and required a Signal to Noise (SNR) of 41 dB. However, by using a polar code R = 1/2 required an SNR of 20.1 dB. The results showed that the utilization of cyclic prefix (CP)-OFDM with channel coding helps the diversity effect of 5G transmissions to achievable.
