Title: Spread spectrum demodulator
Inventor: OKAMOTO NAOKI
IPC: H04B1/71
Filed: 1991-11-14
Abstract: PURPOSE:To eliminate an interference wave by passing one of halved reception signals through a variable phase shifter, passing the other through a circuit whose phase is unchanged, synthesizing both signals and controlling the phase shift so that the sum output is minimized. CONSTITUTION:A signal inputted from a input terminal 6 is a superimposed wave between a signal component (modulation wave subject to spread spectrum) and an opposite continuous wave noise, and the input signal is halved by a branching device 1. Then the one is subject to phase change by a variable phase shifter 2 and the other is outputted directly or via a circuit having a loss equivalent to the phase shifter 2 and both signals are synthesized by a multiplexer 3. An output of the multiplexer 3 is detected by a detector 4 and fed back to the variable phase shifter 2 through a controller 5 to control the phase shift of the variable phase shifter 2 so that the detection output is minimized. The signal synthesized by the multiplexer 3 is sent to an inverse spread spectrum section via a terminal 7. Thus, a constant wave(CW) interference and other interference waves are eliminated and the signal is received with excellent C/N.
