Method and apparatus for nonlinear filtering and controlling the peak-to-average ratio |
摘要 |
A method and apparatus for providing a precoder filter having peak-to-average ratio (PAR) controller that also serves as a high-pass, low-pass, or band-pass filter. The described invention is includes a modulo device connected in series with the PAR controller and a precoder filter connected in a feedback arrangement. The input to the apparatus is a sequence of data symbols and the output is a spectrally shaped precoded signal having a controlled peak-to-average ratio.
