The main objectives of this article is to evaluate the performance of different modulation schemes in a 5G communication based on parameters like Bit Error Rate (BER), Peak to Average Power Ratio (PAPR),One-way delay, Spectral efficiency, through-put. The effectiveness of the 5G network in different areas was experimentally proved using various tools for simulation in MATLAB. The Quadrature Phase Shift Keying (QPSK), 16-QAM (16-Quadrature Amplitude Modulation), 64-QAM, and 256-QAM were investigated at the signal to noise ratios (SNR) ranging from -10dB to 20dB at 5dB intervals. The QPSK modulation technique provide the greatest performance with respect to BER, PARP, throughput and latency at the expense of spectral efficiency significantly due to modulation order. For moderate to high SNR, 256QAM shows great results but performance degrades with falling Signal to Noise Ratio and susceptibility to Inter Symbol Interference rises due to the shorter hamming distance. At the lowest SNR of -10dB, 256QA Modulation Technique shows possibly worst numbers – Bit Error Rate of 0.5006bps, almost 0% throughput with a maximum PAP ratio of 8dB, and One-way latency of 5.23ms. Finally, the 64QA modulation technique provides a balanced figures as far as Bit Error Rate, Throughput, Spectral Efficiency and other evaluating parameters are considered with respect to Signal to Noise Ratio of 5dB.
