Abstract
A technique for enhanced reconditioning equalizer filter chain for multi-carrier signals is described. The input to a transmitter chain is modified by an enhanced reconditioning equalizer filter chain, prior to being applied to the transmitter. The enhanced reconditioning equalizer filter chain modifies and smoothen the amplitude of the signal. The modified and smoothen signal has its picks reduced which results to lower Crest Factor. The input to the enhanced reconditioning equalizer filter chain 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 enhanced reconditioning equalizer filter chain. The enhanced reconditioning equalizer filter chain could be implemented in digital or analog domain.
