A communication method for communication between a first and a second communication apparatus, where at least one wanted signal is transmitted from the second communication apparatus to the first communication apparatus is provided. The method includes sending a first carrier signal at a first frequency using the first communication apparatus. The method also includes receiving the first carrier signal using the second communication apparatus and generating a second carrier signal at a second frequency. The method includes changing the second frequency and/or a specified phase angle, and/or modulating the second carrier signal in each case as a function of the wanted signal in order to generate a transmit signal. The transmit signal is sent by the second communication apparatus, and the transmit signal is received and demodulated in order to recover the wanted signal using the first communication apparatus.
