Simulation of Indoor-Outdoor and Outdoor-Indoor Radio Channel in 960-1700 MHz Band

The design of high performance communication systems depends on the previous knowledge of the radio channel dispersive behavior. Through wideband measurements it is possible to measure such dispersion by determining parameters as delay and Doppler spread or coherence time and bandwidth. In this work, measurements carried out on the 910-1710 MHz band in a transition channel (indoor-outdoor and outdoor-indoor) generate data that permit to compare the experimental delay spread with that obtained from the simulation of this channel by using the Saleh-Valenzuela model, which is a model applied to indoor channels. Clusters of multipath in the power delay profiles are used to identify the model parameters, instead of a unique cluster. The parameters of the Turin model, which is a model applied to outdoor channel, are also identified with the same experimental data. The tools used in this paper pointed to the conclusion that the Saleh-Valenzuela model can be used to simulate the transition channel too.
