Abstract

In this paper, we propose a novel template generation method for UWB wireless communications, instead of the conventional matched filter technique. In the proposed scheme, the template waveform is constructed as combinations of orthogonalized elementary waveforms with Fourier coefficients. By adjusting the number of elementary waveforms and their coefficients, it is possible to detect several types of UWB signals. The orders of approximation corresponding to different numbers of elementary waveforms are analyzed and the bit error rate properties are then investigated by computer simulation.
