For the QPSK modulator shown in the figure above, construct the truth table, phasor diagram, and constellation diagram. In Figure 2, it can be seen that with QPSK, each of the four possible output ...
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 ...
The demand for greater data throughput seems endless, and it is accelerating faster than many people expected, creating bottlenecks in fiber-optics networks. Digital transmissions of 100 Gbps, which ...
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 ...
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, ...
With worldwide Internet data traffic increasing by 50 percent each year, telecommunications companies that handle this digital torrent must be able to economically expand the capacities of their ...
SAN JOSE, Calif.--(BUSINESS WIRE)--GigOptix, Inc. (NYSE MKT: GIG), a leading supplier of advanced semiconductor and optical communications components, today announced that it will be showcasing its ...
A single PIC can integrate upwards of fifty optical components that would otherwise each require a separate package. Infinera achieved a record one trillion bits per second (1 Terabit/s) speed on a ...
