Abstract :
The link budget of the transmission gain is usually evaluated by using the Friis´ transmission formula. However, it is not directly applicable to ultra wideband impulse radio (UWB-IR) transmission systems. This paper presents the link budget evaluation formula in the term of transmission gain for the UWB-IR systems that takes into account the transmitted waveform, its distortion due to the antennas, the channel and the correlation receiver. Since the antennas are significant pulse-shaping filters in UWB-IR, the various kinds of the antennas are experimentally examined, especially focused on the effect of the received signal and the isotropic template waveforms.
