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 ...

This paper proposes an improved QPSK modulation scheme, called as π/6-QPSK, which is an improvement of existing π/4-QPSK modulation technique in the wireless communication system in case of phase ...

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 ...

In recent years digital designs have been highly automated, and the digital modulation provides more information capacity, compatibility, higher data security, better quality communications and ...

QPSK, or quadrature phase shift keying, is a digital modulation technique that encodes two bits per symbol by varying the phase of a carrier signal. It is widely used in wireless communications ...

In this paper, the authors are implemented BPSK modulation technique, a subsystem module of digital communication using reversible logic. Later on they have implemented a QPSK modulation technique ...
