Abstract
The present invention provides a novel technique for reducing the effect of CMI for PPM UWB signals. The system and method in accordance with the present invention greatly improves the performance of receivers and eliminates the possibility of catastrophic errors. The proposed technique introduces a variable modulation index instead of a fixed modulation index as was previously known in the art. The modulation index is changed over each frame within each symbol. In other words, a time hopping modulation index sequence is used over the frames of the UWB symbols in accordance with the present invention.
