Patent ID: 8379770

Claim:
A system for converting a received radiofrequency signal S RX in order to recover encoded data carried by signal S RX , comprising: generating means arranged so as to generate a signal S LO ; mixing means arranged so as to generate a signal S RX-LO by mixing signal S RX and signal S LO ; an analog/digital converter arranged so as to convert signal S RX-LO into a digital signal S RX-LO-Num ; a device generating an error correction digital signal S Cor , the device being arranged so that digital signal S Cor reflects a phase gap between the phase of signal S LO and a phase setpoint, the phase setpoint being a phase of an ideal signal S 0 , ideal for recovering the encoded information carried by signal S Rx ; and combination means arranged to generate signal S 0′-Num by combining signal S RX-LO-Num with digital signal S Cor .
