Abstract

The invention relates to a method for receiving data frames which consists of determining a reference frame by firm decisions on the value of each bit received and then verifying the reference frame according to an integrity check code used for the transmission. The invention includes the following steps: calculating, for each bit of said reference frame, a plausibility value that represents the probability of a transmission error; and, in the event of incompatibility with said integrity check code, identifying in said reference frame a non-empty finite set of the most plausibly erroneous bits in accordance with said plausibility values; listing candidate frames each corresponding respectively to one of the possible combinations of numbers of reversals of the identified most plausibly erroneous bits; and verifying the compatibility of the listed candidate frames with said integrity check code.

The invention relates to a method for managing transmissions of digital data in a remote-reading apparatus including a plurality of metering devices provided with a radiofrequency module for communicating with a radiofrequency transceiver device of a gateway system of said apparatus, said method including a step of transmitting a digital signal from said radiofrequency module to said radiofrequency transceiver device and/or from said radiofrequency transceiver device to said radiofrequency module, said transmission being carried out via a modulated carrier in accordance with a frequency-shifting modulation, said method being characterised in that said modulation has a modulation index which is strictly equal to an integer value divided by two and in that said method includes a step of receiving the signal transmitted according to said modulation, including operations of generating a synchronisation signal synchronised with the received signal and of synchronously detecting the received signal by means of said synchronisation signal.

Abstract

The present invention describes a method implemented by a radiofrequency device of a gateway of a remote-reading apparatus which also includes a plurality of meters, the gateway also including a hub communicating with said radiofrequency device as well as with an external telecommunications network, the method including the steps of: receiving from the hub a downstream gateway signal produced in accordance with a network synchronisation signal from a clock of the external telecommunications network; and adapting the radiofrequency transmissions to the meter and/or the radiofrequency receptions from the meter using said received downstream gateway signal, such that the phase and/or frequency of said radiofrequency transmissions and/or receptions are phase-synchronised in accordance with the network synchronisation signal.
