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 wi

Multicarrier modulations attract a lot of attention ranging from wireline to wireless communications compared to single carrier modulation because of theirs capability to efficiently cope with frequency selective fading channels. Much of attentio

As a multicarrier transmission system Orthogonal frequency division multiplexing (OFDM) has been widely applied in wireless communication systems due to its numerous advantages like robustness against multipath fading and delay, high data rate tr

Several approaches to combine multicarrier modulation with code-division multiple access (CDMA) techniques have been proposed with the aim of bringing the best of both worlds to wireless communications [1]. Among these, multi-carrier CDMA (MC-CDMA),
