Abstract
Pulse design is examined for multiple access ultra- wideband communication systems with consideration of the transmitter pulse-shaping and the receiver filter at the same time, subject to a transmitter power constraint. It is shown that an appropriate sine pulse not only conforms to required spectral emission constraints, but also optimizes the signal-to-noise-plus- interference ratio of the ultra-wideband system when corrupted by multiple access interference. Compared with previously proposed pulse shapes, the sine pulse proposed here achieves better error rate performance in multiple access environments without adding any implementation complexity. The design of ideal ultra- wideband pulses is clarified in terms of properties of the spectral emission mask.
