Thus, various services can be achieved with these networks for different terminals from voice and multimedia data services over the mobile phone and achieve better packet transmission over the cellular networks. The practical application system also considers orthogonal subcarrier-based waveforms to meet the demands of the next-gen 5G networks. Also, the 5G networks for asynchronous transmission require proper localization property in the time domain so that low latency can be achieved inefficient transmission of the small packet. To address the localization issues, more flexible waveforms need to be generated. Hence, the paper introduces a futuristic (5G) communication system performance enhancement by generating (downlink) waveform. The system performance is measured by considering signal to noise ratio (SNR), spectral density, and throughput. The outcomes show that the futuristic (5G) communication system yields better SNR with enhanced throughput, increased spectral density in the 5G obtained than of LTE, and yields higher subcarrier space that reduces the Cyclic Prefix.
