Optoplex's passive free-space micro-optics-based90º optical hybridis suitable forcoherent signal demodulationfor either homodyne or heterodyne detection. The patent-pending, broadband device accepts the two optical signals (S & L) and generates four output signals: S+L, S-L, S+jL, S-jL, ...
and demodulation. The transition from analog communication to digital has advanced the use of QPSK. Euler's relation is used to assist analysis of multiplication of sine and cosine signals. A SPICE simulation is used to illustrate QPSK modulation of a 1MHz sine wave. A phasor diagram shows ...
The purpose of this note is to show how SystemView, by Elanix, may be used to simulate quadrature phase shift keying (QPSK) modulation and demodulation in a communication system with ideal components. In this application note, the following subjects or areas of design are covered: The s...
May 1 2002 Abstract Readers are presented with step-by-step derivations showing the operation of QPSK modulation and demodulation. The transition from analog communication to digital has advanced the use of QPSK. Euler's relation is used to assist analysis of multiplication of sine and cosine signa...
The second output of the block is a Boolean scalar indicating if the first output is a valid frame with the desired header and if so, enables the Data Decoding subsystem to run. Data Decoding The Data Decoding enabled subsystem performs phase ambiguity resolution, demodulation and text message ...

The present invention generally relates to an AFC circuit, and more particularly, to an AFC circuit for a QPSK demodulator which is effective for a QPSK (quadrature-phase shift keying) modulated signal demodulation system which is utilized in fields of a satellite communication or a satellite broad...
FIG. 2 shows a receiver block diagram for demodulation of a noise-encumbered receiving signal r(t). Incoming receiving signal r(t) is mixed down to baseband with the help of mixers 6.1, 6.2, and a separation into I and Q components takes place. This separation into I and Q components ...
