Abstract
A communication system (1 ) comprising at least one transmitter (3) arranged for transmitting a transmission signal modulated to a carrier wave frequency and at least one receiver (2) arranged for calibrating to the carrier wave frequency of a transmitter (3). The bandwidth of the transmission signal transmitted by a transmitter (3) is so much smaller than the transmission bandwidth that is available for a communication link between a transmitter (3) and a receiver (2) that the frequency of the transmission signal transmitted by the transmitter (3) is within the available transmission bandwidth upon variation of the carrier wave frequency within a predetermined range. The receiver (2) is arranged for calibrating to a carrier wave frequency transmitted by the transmitter (3) for the purpose of demodulating the transmission signal.
