| 20080266177 | High Resolution, Arbitrary-Even-Order Direction Finding Method and Device - Method of high-resolution direction finding to an arbitrary even order, 2q (q>2), for an array comprising N narrowband antennas each receiving the contribution from P sources characterized in that the algebraic properties of a matrix of cumulants of order 2q, C | 10-30-2008 |
| 20090073041 | 1D OR 2D GONIOMETRY METHOD OF DIFFUSE SOURCES - A goniometry method for one or several diffuse (or distributed) sources is disclosed. The sources or sources having one or more give directions and a diffusion cone. The sources are received by an array of several sensors. The method breaks down the diffusion cone into a finite number L of diffusers. A diffuser has the parameters (θ | 03-19-2009 |
| 20090220031 | METHOD FOR BLIND DEMODULATION AT HIGHER ORDERS OF SEVERAL LINEAR WAVEFORM TRANSMITTERS - Disclosed is a method of blind demodulation of signals arising from one or more transmitters, the signals including a mixture of symbols comprising at least one step of separating the transmitters by using the temporal independence of the symbol trains specific to a transmitter and the mutual independence of the transmitters. | 09-03-2009 |
| 20090305720 | METHOD FOR CHARACTERISING EMITTERS BY THE ASSOCIATION OF PARAMETERS RELATED TO THE SAME RADIO EMITTER - Method of using one or more transmitters and/or one or more parameters associated with a transmitter by using a reception station comprising a device suitable for measuring over time a set of K parameters dependent on the transmitters associated with vectors {circumflex over (η)} | 12-10-2009 |
| 20110025563 | METHOD FOR MEASURING INCOMING ANGLES OF COHERENT SOURCES USING SPACE SMOOTHING ON ANY SENSOR NETWORK - A method for interpolating steering vectors a(θ) of a sensor network, the sensor network receiving signals transmitted by a source, characterized in that, for the interpolation of the steering vectors a(θ), use is made of one or more omnidirectional modal functions z(θ) | 02-03-2011 |
