“…Over the past decade, the need for high-speed data communication and advanced signal processing has fueled numerous research efforts [1], [2], [3], [4], [5], [6], [7], [8]. Among other multi-carrier modulation techniques, orthogonal frequency division multiplexing (OFDM) has been extensively studied in communication systems as one possibility to meet the exponential rise of internet traffic requirements [1], [2], [3], [4], [5], [6], [7], [8], [9]. OFDM is well known for its many advantages such as subcarrier flexibility, and high spectral efficiency [1], [2], [3], [4], [5], [6], [7], [8], [9].…”
