摘要： The invention relates to a method for transmitting digital data over a communication channel, between a transmitting base including N transmitting antennas and K receivers. A carrier signal of frequency f
0 and M sub-carriers of index m are used, which are suitable for transmitting, in parallel, K digital data streams sk between the transmitting base and each receiver. The method includes a step in which N.M complex symbols t
n (m) are calculated from K.M symbols s
k (m), by t
n (m) = formula (I) α
k .H
k,n
* (m).s
k (m), where * denotes a complex conjugate value, H
k,n (m) is a complex value estimating the transfer function of the communication channel between the transmitting antenna n and the receiving antenna k, at a corresponding frequency of the sub-carrier m, and α
k is a standardizing coefficient.-

摘要： Method for measuring a physical parameter in soft tissues of a mammal, in which a mechanical shear wave is propagated through the soft tissues and observation of the propagation leads to determine values of a shear wave propagation parameter. The physical parameter is computed on the basis of these values.

摘要： Method for measuring heart contractility of a patient, in which a mechanical shear wave is propagated through the heart and observation of the propagation leads to determine a shear wave propagation parameter representative of the elasticity of the heart. The value of the propagation parameter at the end of a systole is sampled, which leads to a parameter representative of the end systolic elastance.

摘要： The invention relates to a wave-propagation-based sounding method, in which: an incident wave is emitted through a medium (1) including diffusers (2) capable of reflecting the wave; and, subsequently, signals representing a reflected wave reverberated by the medium from the incident wave are captured, said captured signals being the sum of a single scattering component and a multiple scattering component. The captured signals are processed by separating the multiple scattering component from the single scattering component by filtering at least one frequency transfer matrix representing responses between transducers from the transducer assembly.

摘要： A method for generating photons by sonoluminescence, from a bubble of gas trapped in a liquid reservoir (2) by a stationary ultrasonic wave. An ultrasonic pulse which is emitted by several high frequency transducers (T1-T8), which are pre-focused onto the gas bulb and synchronized with the light emissions of the gas bubble during an initial learning phase during which the focusing and synchronization are optimized, is superposed on the stationary wave

摘要： The invention relates to a non-invasive method of obtaining an acoustic wave field in the brain (19) using a network (17) transducers, which is positioned outside the skull (14). The inventive method comprises an information acquisition phase, whereby a three-dimensional image of the porosity of the skull at every point is used to determine, by means of digital simulation, the elementary acoustic signals to be emitted by the transducers in order to obtain the acoustic wave field in the brain. After said information acquisition phase, the transducer network is used to locate, by means of ultrasonography, the relative position of the transducer network on the skull and to provide a precise position for said network.
