Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...
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 ...
Optical communication systems have evolved significantly over recent years with the advent of advanced modulation techniques designed to enhance spectral efficiency and mitigate interference. Offset ...
