We introduced the underlying mathematics of symbol error analysis for digital communication systems in August, using the simplest case of BPSK. We concentrated on the ...

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 ...

One of digital communication's most useful tools, both analytically and practically, is the constellation diagram. These diagrams encompass signal constellations, which chronologically and ...

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, ...
