摘要：Although tremendous progress has been made in the area of wireless communications based on orthogonalfrequency division multiplexing but still there exist some problems. In literature so many works has beenreported to resolve the issues but still Peak to average power ratio is still area of concern. In this paper,instead of spectral efficiency we make use of HPA (high power amplifier) weights to resolve the issue ofPeak to average power ratio. 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 PAPRis smaller than that of the clipping and filtering (C&F) methodology, and also the bit-error-rate (BER)performance of the weighted OFDM system is improved compared with the C&F methodology. Here, theprojected methodology is easier than the C&F method
