Receiver

Abstract

Abstract PURPOSE:To realize simplified constitution without need of synchronizing carrier waves of each polarized wave side, by using a modulation wave of one polarized wave side and a signal obtained from a recovered carrier of other polarized wave side to generate a signal through interference compensation. CONSTITUTION:The receiver consists of a carrier recovery devices 1, 2, orthogo nal detectors 3-6, A/D converters 7-10, transversal filters 11, 12, control circuits 13, 14 for the transversal filters 11, 12, and subtractors 15, 16, and a modulation wave of one polarized wave side and a signal obtained from a recovered carrier of other polarized wave side are used to generate a signal through interference compensation. Thus, the a signal for interference compensation is surely synchro nized with the compensated modulation wave and it is not required to synchro nize carriers of each polarized side, thus the constitution is made simple and inexpensive.
