COMPARATIVE ANALYSIS OF FBMC AND OFDM MULTICARRIER TECHNIQUES FOR WIRELESS COMMUNICATION NETWORKS

    Multicarrier techniques are highly attractive for the development of modern wireless communication systems such as 4th 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 project presents the performance analysis of 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 Matlab Software.

Design parameters,

  1. Modulation: 4-OQAM for FBMC and 4-QAM for OFDM
  2. FFT Size: (32,64,128,256) and
  3. Sub-carrier: (16,32,64,128).
