On Time-of-Arrival Statistic of Gaussian Channel Model
A model of an angle-spread source, termed the "Gaussian Channel Model" is considered. The cumulative distribution function of the Time-of-Arrival of the multipath components is derived for an arbitrary angle spread. The simple approximate expressions for the Time-of-Arrival cumulative distribution function and probability density function are proposed. Numerical results obtained with the help of the derived expressions show the good coincidence with the experimental data and other known results. The implementation of smart antennas at Base Stations (BS) gives the opportunity to significantly enhance the performance of wireless networks.
