Digital terrestrial broadcasting systems will use the QPSK-OFDM (Orthogonal Frequency Division Modulation) modulation scheme because of its robustness in mobile environments. This report describes an ...

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 ...

Bandwidth variable transmitter (BVT) is one of the key enabling technologies for future EONs. In the University of Bristol's lab, transmitters are designed to generate optical signals with variable ...

Eliminating software adjustments in circuits based on digital logic improves robustness and reduces cost for small-production-run series. This circuit is a cost-improved version of classical QPSK ...
