Abstract

Fifth generation (5G) New Radio (NR) cellular communication with data transfer rates up to 20 Gbps using high frequencies of 6 GHz - 100 GHz. Using a high frequency, the channel will be sensitive to natural conditions, and human blockage. This study analyzes the comparison of the performance of the 5G channel model with and without the influence of human blockage. The research method uses a frequency of 3.5 GHz with a bandwidth of 99 MHz using Cyclic Prefix-Orthogonal Frequency Division Multiplexing (OFDM) on Quadrature Phase Sshift Keying (QPSK) modulation. Research on the 5G channel model represented in the representative Power Delay Profile (PDP) obtained 37 paths with and without the influence of human blockage. The results of the study show that to get outage performances of 10-3, it requires a Signal to Noise Ratio (SNR) of 22 dB with the influence of human blockage and an SNR of 22.3 dB without the influence of human blockage (non-human blockage). The Frame Error Rate (FER) performance at 10-3 requires an SNR of 46.5 dB with the effect of human blockage and an SNR of 46.8 dB for non-human blockage. Bit Error Rate (BER) performance to reach 10-4 requires an SNR of 35dB with the influence of human blockage and an SNR of 35.5 dB non-human blockage. The results show that human blockage at a frequency of 3.5 GHz can affect the performance of the 5G system and requires strong codes to minimize errors such as convolutional, polar, and repetition codes. Keywords: 5G, human blockage,Outage Probability, Frame Error Rate, Bit Error Rate.
