Abstract
The era of 5G communication has to offer a futuristic way of technological advancement in mobile communication and also it has been said that 5G can able to provide higher transmission rate, user-friendly experience, resource utilization, etc. To achieve this 5G technology needs to have support towards small data packets and narrow bands with low power consumption. However, the existing Orthogonal Frequency Division Multiplexing (OFDM) have issues with high side lobes causing undesired leakage, channel interference and high peak to average ratio (PAPR). This paper deals with contextual applicability of modulation schemes especially OFDM as well as filtered OFDM (F-OFDM) to be synchronized with 5G communication scenario. In the time domain OFDM symbol, to improvise the out of band (OfB) radiation of the sub band signal during the process of management of complex domain orthogonally of symbols, a specially designed filter is proposed. The performance evaluation is done among optimized filtered OFDM (F-OFDM) with Cyclic Prefix OFDM (CP-OFDM). From the outcomes, it is found that the streamlined F-OFDM system has got better PAPR value than conventional OFDM system with least Bit Error Rate (BER) at 20 dB of SNR. Through the optimized F-OFDM system spectrum efficiency is enhanced.
