A New Scheme For Reduction Of Peak-To-A Verage Power Ratio In Orthogonal Frequency Division Multiplexing

Orthogonal Frequency Division Multiplexing (OFDM) is an attractive modulation method for channels with a non-flat frequency response. as it saves the need for complex equalizers. However. its main disadvantage is the high peak-to-average power ratio (PAPR) of the output signal. which may take val...
