Abstract: The invention relates to a method of initializing an electronic radio communication module making it possible to execute a radio communication program, stored in a first non-volatile memory, the initialization being based on values of calibration parameters. According to the invention, the method comprises the following steps, performed by the module when it executes the program: reading (E11) of at least one compressed calibration parameter in a second non-volatile memory; decompressing (E12) each compressed calibration parameter read, so as to obtain a decompressed calibration parameter; and initializing (E14) the module, based on the values of the decompressed calibration parameters.
