Method and system for reducing peak-to-average power for OFDM signals |
摘要 |
The invention provides a system and method for effectively reducing peak-to-average power ratio (PAPR) in an OFDM signal. The method includes the steps of oversampling a signal in the time domain, gradually clipping an amplitude of the signal to a predefined level using a formula involving a hyperbolic tangent, bandpass filtering out-of-band spectral components of the signal due to non-linear clipping to be within a predetermined mask, and transmitting the signal.
