Indoors Radio Channel Simulator

In this work we develop a program, to obtain the impulse response, by simulation, of the wide band radio channel in indoors. This program generates a sequence, in successive runs, of channel impulse responses, over different transmitter - receiver separation distances. Generating: amplitudes, delays and phases; of the paths arriving to the receptor, based on a statistical model, the model parameters are introduced by the user, matching, in this way, the simulation with the desired environment. Having too, as user entries, the transmitter and receiver antenna gains, the operation wavelength and the receiver sensitivity. The program was implemented in MATLab™ 6.5 and, it counts with a friendship interface, operating by means of menus, easy to use, from where, the user introduces the parameters and data. As result, of one simulator run, obtains, a impulse response graphic, amplitudes vs. arrival times, and a file that contains, for every simulated path, amplitude, arrival time and phase; in a results table. And, with successive runs, obtain in other results table, the radio channel parameter, such that: total multipath gain, path loss, rms delay spread and excess delay.
