摘要：In this paper, a peak-to-average-ratio (PAPR) reduction scheme supported a weighted orthogonalfrequency-division multiplexing (OFDM) signal is projected to cut back the PAPR while not distortion in removingthe burden at the receiver aspect. within the projected theme, a weight is obligatory on every separate OFDM signalvia a definite reasonably a band limited signal, associate degreed an OFDM signal fashioned with the weightedseparate data is then thought of before a high power electronic equipment (HPA), whereas the original signal are oftenrecovered fully at the receiver aspect. Meanwhile, the time period required to transmit the weighted OFDM signal isthat the same because the time period for the first OFDM signal. The performance of the proposed scheme isestimated with Mat lab Simulator. With respect to the theoretical analysis, the weighted OFDM signal PAPR issmaller than that of the clipping and filtering (C&F) methodology, and also the bit-error-rate (BER) performance ofthe weighted OFDM system is improved compared with the C&F methodology. Here, the projected methodology iseasier than the C&F method.
