This paper presents a simulation model for a 7 rays empirical-based model of an indoor gigahertz wireless mobile channel with randomized distortions both in time and frequency. Unlike statistical models such as the Rayleigh or Rician fading channel models frequently used in many literatures, the empirical-based model presented here makes few assumptions and is simulated at a wideband frequency in the gigahertz range. Wireless system transmitting at such high frequencies suffers greatly from channel distortions and multipath effects. The presented model takes into account the varying effects of magnitude attenuation, phase distortion and delay fading for a mobile system in an indoor environment. Following the work of Rustako et al., a basic 7 rays model is used to represent the minimum number of radio paths taken by a wireless transmission within an empty rectangular room. The accuracy of the model is examined by comparing the simulation results with empirical measurements recorded in a laboratory environment at the Cooperative Research Centre for Broadband Telecommunications and Networking and measurement findings presented in [2].
