Abstract

Peak to Average Power Ratio (PAPR or PAR) is main problem of Orthogonal Frequency Division Multiplexing. The Classical Clipping method is focused in this paper for reduction of PAR using different modulation techniques. Through the Analysis, it is shown that Clipping using QPSK is better than BPSK.
