Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation and multiplexing technique
proposed for 3G, 4G LTE-A systems to achieve higher data rates with better spectral efficiency at low latency. Time
varying nature of the wireless channel can cause frequency selectivity and multipath fading which affects performance of
the system badly.
