5G Modulation Technique Comparisons Using Simulation Approach

The objectives of this paper are to look at performance parameters including bit-error-rate (BER), throughput, spectral efficiency, peak-to-average power ratio (PAPR), and one-way delay for various modulation schemes utilized in a 5G wireless network. The Quadrature Phase Shift Keying (QPSK), 16QAM (16-Quadrature Amplitude Modulation), 64QAM, and 256QAM were investigated at the signal to noise ratios (SNR) ranging from -10dB to 20dB at 5dB intervals. The effectiveness of the 5G network in different areas was experimentally proved using MATLAB simulation. The QPSK MCS demonstrated the greatest performance in BER with 0 bps at all SNRs, throughput of 100%, PAPR of 3dB, and one-latency of 1.75ms. However, because of the tiny modulation order, it experienced a significant loss in spectral efficiency. When the SNR is between 10 and 15dB, 256QAM may be the best option. However, it works extremely badly when the signal-to-noise ratio is low, owing to the shorter hamming distance between the symbols, which makes it susceptible to Inter Symbol Interference (ISI). At the lowest SNR of -10dB, 256QAM has a BER of 0.5008bps, 0% throughput, a maximum PAPR of 7dB, and a latency of 5.25ms with a block error probability of 1. The 64QAM modulation technique provides a decent balance with a respectable SNR of 5dB. It has a BER of 0.0, a throughput of 100%, and a spectral efficiency of 0.0295 bps/Hz.
