O knihe
Future mobile communications systems reaching for ever increasing data rates require higher bandwidths than those typical used in today's cellular systems. By going to higher bandwidth the (for low bandwidth) flat fading radio channel becomes frequency selective and time dispersive. Due to its inherent robustness against time dispersion Orthogonal Frequency Division Multiplex (OFDM) is an attractive candidate for such future mobile communication systems.Pulsating OFDM symbols spread the spectrum of the modulated signals in the frequency domain, leading to a spreading gain that is equal to the inverse of the duty cycle of the pulsed sub carriers. We studied the spectral characteristics of pulsed OFDM and the added UWB
