Abstract
Based on the Schmidt orthogonalization and combination of pulses, a new class of pulse waveforms for the cognitive ultra-wideband communications are proposed, simulation results and the processing algorithm indicate the waveforms: the spectrum utilization ratio is higher, the orthogonality of the pulses is good both before and after suppressing NBIs, which is suitable for the multi-user communication.
