Abstract :
We investigate the peak-to-average power ratio (PAR) and its effects on the performance of Zipper-VDSL systems. The spectrum and the out of band power when passing through a nonlinear device is also investigated. We further evaluate the performance with a recently proposed PAR reduction technique for orthogonal frequency division multiplexing (OFDM). PAR reduction of Zipper-VDSL minimizes the distortion and out of band power of the signal, reducing the dynamic range of transceiver components and near-end crosstalk (NEXT)
