  • Patent number: 7457268
    Abstract: The invention relates to a method for the allocation of packets on a carrier containing timeslots, comprising the step of defining an interleaving length and an allocation window characterized in that packets are allocated within groups defined by the power needed for the transmission and that the size of groups is at most equal to the interleaving length.

  • Patent number: 7042966
    Abstract: A method for estimating a signal-to-noise ratio, in particular digital, received by a radio communication receiver. The method includes estimating separately the signal and the noise and filtering (36, 44) separately the signal (Eb) and the noise (N0) before carrying out the division (40) of the signal from the noise. The noise filtering is for example of the statistical type, whereas the signal filtering is of the low-pass filtering type.

  • Publication number: 20040157553
    Abstract: The invention pertains to a method for assigning communication resources in a telecommunication system, in which the communications are relayed by satellites covering an area of land that is divided into zones. Each zone has a communication resource pattern formed, on the one hand, by the directions of the satellites seen from the zones and, on the other hand, by frequency sub-bands and/or polarization. These resources are distributed so that two adjacent zones comprise different resources. The patterns of two zones are distinguished only by the direction of the satellite(s) that are assigned to the zones having this pattern. In one embodiment, all of the frequency resources are assigned to all the zones and the patterns are only distinguished by the directions of the satellites that supply these resources.

  • Patent number: 6690935
    Abstract: The invention concerns a method of transmitting non-dated digital data between a transmitter and a receiver in which the data can take at least two different paths between the transmitter and the receiver and handover from one path to another occurs during transmission. In the transmitter, packets intended for the second path are transmitted only after the last packet intended for the first path has been transmitted and in the transmitter and in the receiver packets on the first or second path are delayed in order for packets on the second path to arrive after packets on the first path. It is therefore not necessary to transmit signaling to differentiate the two paths at the receiver, which can include a single demodulator.

  • Patent number: 6539214
    Abstract: The invention concerns a method of estimating the noise power of a given digital signal (cell1) assigned a code, this signal being received by a receiver (56) simultaneously with a plurality of other digital signals assigned different codes. The noise powers are estimated for each of the received digital signals (cell1, cell2, . . . cellM) assigned codes and there is assigned, to the given signal, the mean noise power (62) which is the ratio between, on the one hand, the sum of the estimated noise powers and, on the other hand, the total number M of received codes.

  • Patent number: 5881367
    Abstract: In a telecommunication network, the power of a first signal transmitted via a satellite by a first station to be received in the form of a second signal by a second station is regulated. At a given time, a value representative of a signal-to-noise ratio of the second signal is predicted for a later time, and, at an intermediate time, the power of the first signal is regulated in the first station as a function of the predicted value. The intermediate time precedes the later time by a time period substantially equal to the propagation time between the first and second stations.

  • Patent number: 5828947
    Abstract: The invention provides a method of regulating the power of transmission between first and second stations in a multiple satellite visibility satellite telecommunication network. The method comprises the following cyclic steps: regulation, for each of said N channels, of an isolated transmit power level command signal such that when it commands the power at which the first station transmits the first isolated signal in each channel the quality level of the corresponding isolated second signal received by the second station is equal to a reference quality level, and regulation, for all of the N channels, of N combined transmit power level command signals such that when they command the levels at which the first station respectively transmits the N first combined signals on the N channels the quality level of the global signal received formed from the N combined second signals is equal to the reference quality level.
