This demodulator is suitable for the quadrature phase-shift keying (QPSK) modulator previously published by the same author, "Novel Low-Cost QPSK Modulator Needs No Adjustments" (electronic design, ...
Free Space Optics is the technology which implies the line-of-sight link for the transfer of data between two distant points. The beam of light is used to provide optical connection that can transmit ...
Since the early days of electronics, as advances in technology were taking place, the boundaries of both local and global communication began eroding, resulting in a world that is smaller and hence ...
Quadrature phase shift key is a one of the digital modulation schemes that use Phase-shift keying. One popular varient of QPSK is offset QPSK or OQPSK. What is the difference between these two ...
