Telkom University 5G Channel Models Under Foliage Effect and Their Performance Evaluations

This paper proposes Telkom University 5G channel model under foliage effect. The channel model is obtained from series of computer simulations by considering operating frequency of 3.3 GHz, bandwidth of 40 MHz, and real-field parameters of Telkom University environments. We also present the performances evaluation including the outage performance evaluated under Telkom University 5G channel model with and without foliage effects. The bit error rate (BER) and block error rate (BLER) curve of cyclic-prefix orthogonal frequency division multiplexing (CP-OFDM) numerology zero with 5G New Radio (NR) complex-binary phase shift keying (C-BPSK) and Polar codes are presented in this paper to validate the outage performance of Telkom University 5G channel model. We found that the Telkom University 5G channel model has 16 paths for the case of model without foliage effect and has 8 paths for the case when foliage effect is taken into account. The results show that foliage attenuation causes performance degradations indicated by worse outage performance and smaller number of paths at 3.3 GHz frequency. The obtained outage performance from the proposed Telkom University 5G channel model is expected to be a reference for 5G system implementation in Telkom University and Indonesia such that an optimal 5G system implementation in Telkom University and Indonesia can be achieved.
