چکیده

Orthogonal Frequency division is an emerging modulation technique that provides high spectral efficiency and bandwidth. It has a drawback of high Peak to Average Power Ratio. In this paper we discuss a new clipping and filtering approach which is based on cancellation of clipping noise to overcome the drawback of PAPR in OFDM. This method requires only single iteration to resolve the problem of PAPR. The simulation shows that the QPSK modulated OFDM signal with 1024 subcarriers achieve a PAPR reduction to a 2dB.

Analysis of PAPR Reduction Techniques in OFDM

Presently, orthogonal frequency division multiplexing (OFDM) as a multicarrier transmission system is widely used. Along with its advantages it has many disadvantages. One of its major drawback is high peak to average power ratio (PAPR). As with high PAPR the spectral efficiency of the high power amplifiers degrades. So it becomes necessary to maintain the efficiency of a wireless system to red...
