Abstract

In the ever-evolving world of technology, there are many user requests for high data transfer speeds. The presence of the fifth generation (5G) New Radio (NR) cellular communication technology which has a speed of up to 20 Gbps is expected to meet the needs of stable and equitable data services for users of 5G NR network technology. This study analyzes repetition codes using 5G channels with the influence of human blockage at a frequency of 3.5 GHz. This study uses channel coding repetition codes with quadrature phase shift keying (QPSK) modulation with cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) and coding rate R= {1, 1/3}. This study will evaluate the performance of bit error rate (BER) repetition codes which will be compared with uncoded (CP-OFDM). With the addition of repetition codes in the test, it is expected to be able to minimize errors that occur in the system. The results of this study indicate that the 5G human blockage system will affect the number of paths received at the receiver. the receiver gets a representative PDP of 28 paths, after modification it gets 9 modified paths, and at an average BER of 10-3, the performance of BER repetition codes influenced by human blockage requires a signal to noise ratio (SNR) of 17 dB and the performance of uncoded BER requires an SNR of 25 dB. On average BER 10-4, the performance of BER repetition codes requires a signal to noise ratio (SNR) of 24 dB and the performance of uncoded BER requires an SNR of 35 dB. While the performance results for the QPSK BER theory require an SNR of 35.2 dB. The results show that the addition of channel coding repetition codes on the 5G channel at a frequency of 3.5 GHz is able to reduce the SNR value and can affect the performance of the system.
