Abstract:
5th Generation of mobile communication promises to deliver the data rates and services, which 4G could not deliver. To meet the demands and pre-foreseen requirements a complete new system is required incorporating the merits of the previous generations and subtracting the demerits. Internet of things (IoT’s) and machine type communications (MTC) accelerates the keenness to redesign the whole architecture starting from physical layer to higher ones.
This Research work aims to propose a waveform, filter bank multi carrier (FBMC) for the foreseen scenarios of 5th generation of telecommunication and compares the results with 4th Generation OFDM waveform. Filter banks are the advanced forms of multicarrier sub band processing and aims to deliver much better results than OFDM. These filter banks exploit the shortcomings of fast Fourier transforms at the trade-off of adding complexity to the systems i.e. Poly-Phase Filter Networks (PPN). This research work further discusses the waveform contenders for 5G physical layer, which include Universal Filter Bank Multicarrier waveform (UFMC) and Generalized Frequency Division Multiplexing (GFDM). It elaborates the transceiver structures, the modules and filtering techniques involved in the implementation of UFMC and GFDM. By the end of this dissertation, it draws logical and analytical conclusion of the research work.
