Abstract
A method of receiving and processing an RF signal comprises receiving (5) the RF signal; analogue processing the signal and providing a digital output to a digital signal processor, the digital output including an added identification code unique to an RF front end receiver hardware. Within the digital signal processor, the identification code is compared with a predetermined identification code or set of codes to determine if there is match. If there is a (10) match, the digital output is processed to provide data to the user, and if there is not a match, an error function is implemented. This method enables a software developer to make the system function only when there is a match between the hardware and the software. This makes copying the software as difficult as copying the hardware, because (15) copied software will not work with the incorrect hardware batch.
