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