Abstract

It is a challenging task to handle dense multipath environment in a wireless communication channel. Various techniques were suggested to handle this issue such as power control, antenna, time and frequency diversity etc. However, antenna diversity is considered to be the most practical way to handle multipath fading. In this paper, a deterministic UWB channel model was developed based on ray-tracing technique using the art of 3D computer game technology. Reflection, refraction and scattering phenomena were successfully implemented. The model was then enhanced to use multiple antennas on both sides of the system. Simulation results show great improvement in channel impulse response (CIR) in case of multiple antennas. Moreover, the frequency effect on channel impulse response was analyzed for 500 MHz-4 GHz range. Our results indicate that the change in frequency does not affect the channel behaviour a lot but changes the pattern of received rays.
