Abstract

PURPOSE:Two intermediate frequency output obtained by mixing local oscillation output which underwent frequency detuning of 1/2 - to 10-times bit velocity of each other is compounded and then demodulated after amplification and detection. In this way, the instantaneous interruption of reception signal as well as bit error occurrence can be prevented.
