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 signals. A SPICE simulatio...
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 ...
the phase of the recovered carrier is in error, then demodulation The seed value is fully programmable for both configurations. The seed value is reset prior to each burst and is used to calcu- late the randomizer bit, which is combined in an exclusive XOR with the first bit of data from...
QPSK Modulation Demystified Readers are presented with step by step derivations showing the operation of QPSK modulation and demodulation. The move 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 ...
TheData Decodingenabled subsystem performs phase ambiguity resolution, demodulation and text message decoding. TheCarrier Synchronizerblock may lock to the unmodulated carrier with a phase shift of 0, 90, 180, or 270 degrees, which can cause a phase ambiguity. For details of phase ambiguity and ...
