Peak to Average Power Ratio Reduction of OFDM Signals Using Clipping and Iterative Processing Methods
One of the serious problems in any wireless communication system using multi carrier modulation technique like Orthogonal Frequency Division Multiplexing (OFDM) is its Peak to Average Power Ratio (PAPR).It limits the transmission power due to the limitation of dynamic range of Analog to Digital Conv...
