Abstract: As the technology grows in wireless communication, we move towards 5G. In mobile communication, this requires a greater number of users in limited bandwidth, and also the technology used is easily accessible to all. For these requirements, several types of research have been conducted to fulfil these requirements. To provide mobile service to all at a cheap rate a multicarrier modulation technique came into the picture and these multicarrier modulation techniques are used since 4G. An Orthogonal Frequency Division Multiplexing is used in 4G and some modifications in the Orthogonal Frequency Division Multiplexing signal are incorporated to make it suitable for 5G waveform technology. But requirements for 5G are very low out-of-band radiation, low Peak to Average Power Ratio, low reliability, and low latency communication, for enhanced mobile broadband. This paper investigates Filter Bank Multicarrier Modulation in time and frequency selective channels using Gabor Theory. Performance evaluation for the parameters like Bit Error Rate, Peak to Average Power Ratio, Power Spectral Densities for Filter Bank Multicarrier and Orthogonal Frequency Division Multiplexing in various real-time doubly selective channels TDL-A, TDL-B, TDL-C, pedestrian channel, vehicular channel as suggested by the Third Generation Partnership Project has been done.
