Abstract :
A complete simulation of an ultra-wide band communication system in an indoor environment has been undertaken in the time domain. This utilizes time domain 3-D ray tracing coupled with antenna modeling to provide an overall channel simulation. The time-domain radiating characteristics of different linear antennas in transmission and reception in a typical indoor environment are used as representative of typical antennas. The UWB channel was studied with and without considering antenna effect and the system performance are evaluated accordingly. Broadly, link performance is affected by two different factors: radiation pattern from the antenna and impedance mismatch effects. Both are included in the simulation, results are based on 10 meters distance between the transmitter and receiver and 100 Mbps data transmission rate assumed in a complex indoor environment.
