MC) techniques are highly attractive for the development of modern wireless communication systems such as 4 th Generation (4G) and Long Term Evolution (LTE) systems. So far, Orthogonal Frequency Division Multiplexing (OFDM) is the most popular and highly recommended modulation technique for Dynamic spectrum access (DSA) and Cognitive Radio (CR) applications. Despite their numerous advantages, OFDM system suffers from few drawbacks. Filter bank Multicarrier (FBMC), another modulation technique evolved from OFDM which overcomes these drawbacks is examined. FBMC applies filter banks and omits the severe out of band leakage of OFDM. This paper presents the comparative performance analysis of conventional OFDM system and FBMC system in terms of Signal to noise ratio (SNR), Bit error rate (BER), Packet delivery ratio(PDR) and number of packets dropped with the help of computer simulations performed using NETWORK SIMULATOR NS-2.34.
