Performance assessment of throughput in a 5g system

الملخص EN

This paper discusses the throughput of a fifth generation (5g) new radio (NR) system.

the main goal of this research is to provide and develop a pathway for improving the throughput in the 5g system by investigating and controlling certain effective factors.

the studied factors in this paper are the used modulation technique, the used subcarrier spacing in the default clustered delay line (CDL) channel and the existence of a reflector in a custom cdl channel profile.

it is found that the performance of the throughput is improved for larger subcarrier spacing and lower-order modulation technique.

the existence and position of the reflector located between the transmitter and the receiver will be investigated relative to throughput performance in detail.

both fixed and changeable locations of the reflectors are considered in order to reach an optimal value of throughput.

the results show that the existence of the reflector achieves a better throughput value compared to the one with no reflector.

in the presence of a reflector and at a subcarrier spacing of 30 kHz, the throughput can reach 100% of throughput at 0 dB of signal to noise ratio (snr) compared with only 40% at 0 dB for no-reflector case.-
