Abstract (en)
[origin: WO2005046150A1] The invention relates to a method for the blind demodulation of a linear wave-shape source or emitter in a system comprising at least one source, a network of sensors, and a propagation channel. Said method comprises at least the following steps: the time symbol T is determined and sampled to Te samples per symbol such as T=ITe (I whole); a spatio-temporal observation z(t) having mixed sources which are symbol trains of the emitter is constructed from the observations x(kTe); an ICA-type method is applied to the observation vector z(t) in order to estimate the LC symbol trains { am-i } associated with the channel vectors Hzj = Hz (kj); the LC outputs (Am,j, Hzj) are classed in the same order as the inputs (am-i, hz(i)) in order to obtain the propagation channel vectors Hz, j =, Hz (kj); and the alphaimax phase associated with the outputs is determined.
