Abstract

In this paper, we evaluated the transmission gain of ultra wideband radio by using the Friispsila 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.
