A method is provided for enabling or enhancing a use of voice control in a voice controlled application (VCA) via a development framework. The method includes providing in the framework a plurality of action-context pairs usable in a memory of an application development device, which includes a processor. The action-context pairs serve to direct execution of the VCA, wherein the framework context defines a list of parameters related to the action and their respective value types. At least one of a voice recognition engine (VRE) and a natural language library is provided to match each action-context pair with a semantically related vocabulary. A registration mechanism is provided in the framework, which permits an association to be formed between an action-context pair and a handler in the voice controlled application. An associated development system for developing the VCA and user equipment that executes the VCA are provided as well.
摘要:
A method and apparatus for processing a request to transmit a radio signal emitted by a radio terminal to a radio management module. The radio management module authorizes the radio terminal to emit the radio signal to a radio module associated with the radio terminal. The radio module has optical processing elements connected to one end of an optical link via which the radio signal modulated on the optical carrier is to be transmitted. The method includes the following steps, applied by an optical management module connected to the radio management module: generating an activation request to activate the optical processing elements of the radio module associated with the terminal by transmission-related parameters included in the transmission request, the transmission-related parameters being transmitted to the optical management module by the radio management module, and emitting, to the associated radio module, the activation request to activate the optical processing elements.

A method for scheduling pairs in a plurality of pairs of devices for pair communication in a telecommunication network, each pair of devices including a transmitter and a receiver. The method includes: allocating a different time interval to each of the transmitters for emitting training signals, the training signals allowing determining channel estimates; obtaining channel information from at least one receiver having received training signals emitted by at least one of the transmitters, the channel information being determined by the receiver by analysis of the received training signal, the channel information including a channel estimate of a channel between the receiver and the transmitter that emitted the received training signal; and scheduling for pair communication, in the same time interval, the pairs for which a quality indicator verifies a predefined criterion, the quality indicator being determined using channel estimates obtained from receivers of the pairs in the set.

A method and apparatus are provided for identifying and authenticating a radio tag by a radio reader. The tag forms part of a set of tags in a radio range of the reader and has selected a time slot from a set of available time slots. The method includes: a step of the reader sending a query message during the selected time slot; and a step of the reader receiving a reply message from the tag that selected the time slot. The reply message includes a random value selected by the tag. The tag stores authentication coupons and the reply from the tag received by the reader during the time slot contains, as a random value selected by the tag, a value that is a function of one of the coupons.
摘要:
A method of transmitting data between a transmitter furnished with M>=1 transmission antenna(s) and a receiver furnished with N>=2 reception antennas, in which said data are coded using an OFDM/OQAM modulation having L>=1 subcarriers. The method combines a specific coding/decoding with a precoding by Time Reversal, which can be used in high speed radio communications.

A method is provided for sending at least a first data signal and a second data signal, the data being divided into data blocks of fixed size including a header field of predetermined size, the data signals being sent to at least one data processing device adapted to apply a cyclic autocorrelation function with parameter k enabling the first and second data signals to be identified. The value of the parameter k is a function of a ratio between the size of the data blocks and the predetermined size of the header field. The method includes modifying the size of the header field of the data blocks before sending the first data signal, the value of the parameter k and the size of the data blocks remaining unchanged. A method is also provided for processing signals sent in accordance with the sending method.

A method and apparatus are provided for detecting an object to be detected. The object is associated with a profile, wherein the profile characterizes the reflection of a signal on the object. The method includes, for a device in a telecommunication network, the acts of selecting a first profile corresponding to a first object to be detected; requesting, based on the first profile, a resource allocation to the communication network; receiving the resource allocation from the communication network; transmitting a signal in the direction of a second object using the allocated resource; receiving a reflected signal, corresponding to the reflection of the transmitted signal on the second object; computing a second profile using the received reflected signal; and indicating the detection of the first object to be detected when the second profile matches the first profile.
摘要:
A method and apparatus are provided for locating an obstacle between a transmitter and a receiver. The method includes: determining at least one elliptical ring in which the obstacle is situated, the elliptical ring being defined by two confocal ellipses, having their focuses corresponding to the transmitter and to the receiver, each elliptical ring being associated with a physical echo generated by an obstacle; estimating a distance between the obstacle and a focus as a function of the separation between the confocal ellipses at the obstacle in a plane normal to the axis defined by the focuses so as to obtain a set of potential location zones for the obstacle in the elliptical ring; and lifting the ambiguity between the various potential location zones of the obstacle so as to deliver a location zone of the obstacle.

A parametric coding method and apparatus are provided for coding a multichannel digital audio signal. The method includes a coding step for coding a signal from a channel reduction matrixing of the multichannel signal. The coding method also includes: obtaining, for each frame of predetermined length, spatial information parameters of the multichannel signal; dividing the spatial information parameters into a plurality of blocks of parameters; selecting a block of parameters as a function of the index of the current frame; and coding the block of parameters selected for the current frame.
