In this study, we use various signal constellation diagrams to classify signal modulations into 8 modulation types namely, Binary Phase-Shift Key-ing (BPSK),4-Pulse Amplitude Modulation ...

Here, an amplitude-phase-time block modulation (APTBM) scheme and a corresponding demodulation scheme for resisting amplifier nonlinearity are proposed, establishing a new paradigm for balancing the ...

A large proportion of the carbon emissions associated with wireless communications stem from electricity consumption during operation. Spectral efficiency (SE) and energy efficiency (EE) are ...
