Online published on 30 November, 2021. Abstract 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 quicker system availability with digital services. This paper proposes a QPSK module based on bandwidth efficiency of the QPSK modulator has been implemented with the proposed technique; and thereby compared with the conventional BPSK modulation scheme. Synthesis and implementation of QPSK modulation technique is described viz. subsystem modules of digital communication. The QPSK modulator unit will be modeled using HDL code,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 quicker system availability with digital services. With digital techniques, extremely low error rates producing high signal reliability are possible in communication systems. Digital circuits are also more reliable and can be reproduced at a lower cost than analog circuits. The digital technique based communication systems are highly reconfigurable and programmable. This paper proposes a QPSK module based on bandwidth efficiency of the QPSK modulator has been implemented with the proposed technique. Synthesis and implementation of QPSK modulation technique is described viz. subsystem modules of digital communication. These digital modules are implemented as different modules and used as components in top level entities. Top Keywords QPSK modulator, QPSK demodulator, Bandwidth efficiency. Top |
