In this paper, a Peak-to-Average Power Ratio (PAPR) reduction scheme supported a weighted Orthogonal Frequency-Division Multiplexing (OFDM) signal is projected to cut back the PAPR while not distortion in removing the burden at the receiver aspect. within the projected theme, a weight is obligatory on every separate OFDM signal via a definite reasonably a band limited signal, associate degreed an OFDM signal fashioned with the weighted separate data is then thought of before a High-energy Power Amplifier (HPA), whereas the original signal are often recovered fully at the receiver aspect. Meanwhile, the time period required to transmit the weighted OFDM signal is that the same because the time period for the first OFDM signal.
