ABSTRACT:
A technique for enhanced reconditioning equalizer filter for non-constant envelope signals is described. The input to a transmitter chain is modified by an enhanced reconditioning equalizer filter, prior to being applied to the transmitter. The enhanced reconditioning equalizer filter modifies and smoothens the amplitude of the signal. The modified and smoothened signal has its peaks reduced which results in lower Crest Factor. The input to the enhanced 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 enhanced reconditioning equalizer filter. The enhanced reconditioning equalizer filter could be implemented in digital or analog domain.
