Abstract :
In indoor communications, the multipath propagation is fundamental. Generally, several replicas of the signal impinge in the receiving antenna. When there is line of sight, the received energy will be centered in a single wave. In the opposite case, the energy received in the array, is divided in several directions of the multipath, the signal simulates to have arrived from several sources of signal. In our case, using the results of a measurement campaign of the radio channel frequency response in an indoor scattered environment, we esteem the direction of arrival (DOA) of our signal, using MUSIC algorithm (multiple signal classification) associated with smoothing pre-processing and using MDL (minimum description length) approach proposed by Wax and Kailath for the detection of the number of multipath rays arrived at the antenna.
