摘要： Method of adjustment of a receiver of signals transmitted in bursts in a system where the communications are set up within the context of successive frames comprising slots allocatable to the transmitters for their communications with the receivers. The adjustment of at least one characteristic of the receiver allows it to adapt upon the arrival of the bursts, by taking account of at least one reinitialization parameter for a first burst or adjustment parameter computed by a computation unit (4) from the preamble of the burst currently being received. At least one specified adjustment parameter is determined by a computation unit (4), for a new burst of a communication, by taking into account the part of the signal corresponding to the payload of the burst previously received for this communication, if the new is separated from this previously received burst only by a time which is less than a silence threshold value.

摘要： The invention pertains to a method of communication in respect of transmitting/receiving stations in a wireless communication network, in which method first multi-receiver frames are exchanged between a station and a plurality of other stations and second mono-receiver frames are exchanged between a transmitting station and a receiving station, the first frames being transmitted in an omnidirectional manner. According to the invention, the second frames are transmitted in a directional manner so as to increase the throughput of the network. Furthermore, the transmission in a omnidirectional manner is effected in a more robust fashion than the transmission in a directional manner.

摘要： The invention concerns a method for receiving a multi-carrier signal of reduced complexity when the number of carriers is not high. The method includes: demodulating the multi-carrier signal; converting a received signal received in binary representation into a modal representation in a base of at least two mutually prime numbers on a finite space of size equal to the product of the mutually prime numbers; demodulating including conversion.

摘要： A method of decoding a data signal includes progressively constructing a decoding tree, implementing at least two iterations of the following steps: selecting at least one child node of a current node belonging to a selection interval; storing the child nodes in a first stack; deleting the current node from the first stack; selecting a new current node from the first stack; and if the new current node is a leaf node, storing the path between the root node and the leaf node, in the second stack, and deleting the leaf node from the first stack; otherwise, return to the step of selecting a child node for the new current node. Moreover, the method assigns a probability of likelihood to the bits of at least one symbol of the data signal, taking account of the paths stored in the second stack, and determines a probabilistic estimation of the signal.

摘要： The gain control method for the RF and IF amplification stages of a bursty data frame reception system enables, following a step for evaluating the received signal strength, the gain adjustment step of the RF amplification stage to be temporarily deferred until a frame structure symbol is received, during which the gain adjustment step of the IF amplification stage takes place simultaneously with that of the RF gain, while retaining an overall gain linearly dependent on the input signal strength. The corresponding device comprises a control element 46 which generates the control signal for the RF and IF gain amplifiers
