Abstract— The primary disadvantage of orthogonal frequencydivision multiplexing (OFDM) is the high time-domain peak-toaverage power ratio (PAR) that severely limits the transmitt...
Abstract—The high peak-to-average-power ratio (PAR) of Orthogonal Frequency Division Multiplexing (OFDM) transmission systems significantly reduces the power efficiency or perf...
The primary feature of cognitive radios for wireless communication systems is the capability to optimize the relevant communication parameters given a dynamic wireless channel env...
