Exponential growth in mobile & wireless service subscriptions in recent years and its corresponding data traffic poses a serious threat to wireless communication systems; this triggered research to improve the current wireless system hence 5G gained substantial attention. As the keys enabling features in deploying wireless system, the choice of the multicarrier waveform has a significant impact in designing system transceivers, and further impact the overall system performances. Although the 4G system is successful with CP-OFDM multicarrier, due to overwhelming users' growth, several factors make this system unsuitable to many 5G applications owing to strict synchronization and orthogonality requirement in this multicarrier waveform. This paper aims at modeling and evaluating system using the 3GPP new waveforms proposed for 5G wireless design. System model explores the 4G LTE-Advanced physical layer specifications with additional filtering specifications of 3GPP Technical Report. Results obtained were compared with the existing 4G multicarrier system, which shows an improved system performance with the proposed new waveform.
