ABSTRACT:
A technique for a reconditioning equalizer filter for OFDM and non-OFDM signals is described. The input to a transmitter chain is modified by a reconditioning equalizer filter, prior to being applied to the transmitter. The reconditioning equalizer filter modifies and smoothen the amplitude of the signal. The modified and smoothen signal has its peaks reduced which results to lower Crest Factor. The input to the reconditioning equalizer filter could be a baseband, an intermediate frequency (IF) or radio frequency (RF) signal. When the signal is an IF or RF signal it needs to be down converted to baseband before applied to reconditioning equalizer filter.
