Abstract

This paper proposes a practical and effective modulation technique applicable to pulsed-UWB systems that mimics the desirable, continuous spectrum of a BPSK signal without requiring an inversion in the signal path. This technique can be used for scrambling the spectrum of a PPM signal, or as a replacement for BPSK signaling. It has been implemented in an all-digital, delay line based UWB transmitter in 90 nm CMOS. An analysis of the spectral characteristics of the modulation technique is given, as well as simulation and measured results.
