Sažetak
Ultra-wideband (UWB) impulse radio uses very short pulses whose spectra are regularized by Federal Communications Commission (FCC). One technique to obtain these pulses is shaping. The shaping is realized with a bandpass filter called pulse shaper. Its impulse response approximates an FCC-compliant waveform. In this paper, we propose spectral-efficient shapers whose responses approximate high-order Gaussian and modified Hermitian monocycles. To obtain the optimum shapers, we use least-squares error criterion. Furthermore, for various orders of monocycles, we provide the transfer functions that exhibit high spectral efficiency. Within the FCC UWB passband, the transfer functions of the Gaussian shapers ensure the spectral efficiency up to 89%, whereas the functions of the modified-Hermitian shapers provide the efficiency up to 62%.
