dc.description.abstract The fourth generation (4G) of cellular networks, was initially roll out in 2009/10 by succeeding third generation (3G). The fth generation (5G) is the forthcoming evolution of mobile technology expected to be used by 2020 with a wide range of services and usability beyond the use of 4G [1] [2]. Three main services, enhanced Mobile Broadband (eMBB), Ultra-reliable Low-latency Communication (URLLC) and massive Machine Type Communication (mMTC) will impose di erent requirements on the 5G air interface [2]. Orthogonal Frequency Division Multiplexing (OFDM) have been the most attractive one for the development of wireless communication system like 4G due to several advantages like ease of implementation, immunity to interference, high data rate etc. Whereas 5G will demand more from physical layer than the current OFDM can deliver. Therefore, more waveforms have been proposed to address the challenges of OFDM. In this thesis, we provide analysis and comparison for the candidate waveforms Filterbank multicarrier (FBMC) and Universal- ltered multicarrier (UFMC). To obtain insightful analysis we will not only introduce the basic principle of the waveforms but also reveal the characteristics of each waveforms. Moreover, performance comparison in terms of Power spectral density (PSD), Bit error rate (BER) and spectral e ciency presented. Also computational complexity of waveforms in di erent cases evaluated. Mathematical analysis and characterizations are validated by computer simulation employing Mathlab. The result shows advantages and drawbacks for each modulation schemes. FBMC shows the best spectral leakage among both waveform candidates. This reveals to be almost insensitive to multiuser interference to support di erent use cases with in same bands. UFMC, reveals to be most promising which close to OFDM with advantage of better out-of-band (OoB) emission. Finally, some concepts which should addressed are underlined. en_US
