Abstract (en)

[origin: FR2865872A1] The method involves demodulating a primary signal that delivers primary confidential information related to reception of one of bits of a symbol of a main cluster (2), for each bit of the main cluster. Secondary confidential information related to reception of one of bits of a symbol of a sub cluster (3) is determined, from the primary confidential information, for each bit of the sub cluster, in order to demodulate a secondary signal. An independent claim is also included for a receiver to receive a signal modulated according to a primary symbol cluster, called primary signal.
