Abstract

This paper presented a novel transmitter structure for IR-UWB communications. The structure modulates information after the extremely short pulses being produced, decreasing the transmitted pulse position jitter and enabling the high performance of the whole system. A simple RF pulse modulation circuit was devised for the new structure, which is easily to be implemented. Theoretical analysis indicates that the new structure can achieve high-speed modulation like PPM and BPSK. We further implemented BPSK at a rate of 100Mbps with discrete devices.
