PROCESS FOR ENCODING AND DECODING NUMERICAL DATA FOR LOW POWER RADIO TRANSCEIVERS

摘要

The invention relates to a process for encoding and decoding numerical data for low power radio transceivers. According to the invention, the process comprises a stage for encoding the numerical data sent as data packages, the data being encoded at the data package level, through an analogue signal consisting of a preamble with reception stabilization and synchronization role and a number of signal segments which encode information by changing the phase of a set of sinusoidal carriers between consecutive segments, and a decoding stage during which the received signal is continuously monitored with a view to detecting the synchronization section, based on the evaluation, by means of a block making the comparison with a threshold value, of the value of the function of intercorrelation between the received signal and a pattern corresponding to the synchronization signal, as compared with the energy of the received signal.
