Abstract :
We study the urban mobile communication channel by the time-varying impulse response h(τ,t) using the random linear time-variant (LTV) filter theory. The scattering function, which contains much valuable information of the mobile communication channel, is generated and analyzed in the time-frequency domain. The characteristics of the channel can be efficiently extracted from the scattering function. A measurement-based simulation method and the COST/GSM standard are used as two different approaches. As a result, a set of programs has been developed and utilized under the X Window environment. It can meet most of the common requirements of the system designers and service providers
