Abstract:
1. A method by a transmitter for suppressing peak-to-average-power ratio (PAPR) in Multi-Carrier Code Division Multiple Access (MC-CDMA) and derivative systems, the method comprising: generating, at the transmitter, a plurality of signals encoded and modulated according to MC-CDMA; adding, to a sequence of the signals, a corresponding sequence of Newman phase offsets, wherein each of the signals is added a corresponding phase offset of the Newman phase offsets; generating a converted sequence of signals by applying an inverse Fourier transform to the sequence of signals after adding the sequence of Newman phase offsets to the sequence of signals; applying serial to parallel signal conversion to the sequence of signals after adding the sequence of Newman phase offsets and prior to applying the inverse Fourier transform; and transmitting the converted sequence of signals including the sequence of Newman phase offsets.
