The paper analyzes power spectral density (PSD) of orthogonal pulse-based signals for time hopping ultra wideband (TH-UWB) systems. ...
Our extensive studies show that the PSD of these signals depends not only on the time dithering code and the modulation schemes, but also on the energy spectral density (ESD) of orthogonal pulses. ...
For example, M-ary PSM scheme can be designed by using one pulse position and M orthogonal pulses whereas an M-ary BPSM can be constructed by using one pulse position and biorthogonal pulses. ...
