Channel modelling and simulation for wideband systems

In mobile radio communications, the design of wideband digital data transmission systems for optimum performance under the conditions established by the propagation channel, depends largely on a good understanding of the channel behaviour over a wide bandwidth. If the channel is well characterised, the system can be designed to reduce the effects of any disturbance, in particular, frequency selective fading which causes intersymbol interference and its attendant limits on BER performance. An environment-dependent multipath propagation model has been developed and used in the simulation of the wideband mobile radio propagation channel. Results show that the model predicts very well the effect of the environment on the mobile received signal
