4DQPSK Transceiver Design with Efficient Exploration of Advance Design System (ADS)

The world is advancing at a faster rate. There was a time when wired technology was considered as something unrealistic whereas now people have started discussing wireless technology (WIFI, WIMAX etc). The software ADS is a step towards this development. Advance Design system is a software build for RF and microwave related simulations. Both analog and digital simulations can be performed on the software. There were a number of modulation techniques that could be used to perform the transceiver operation as DQPSK, QAM, 256 QAM, pi/4 DQPSK etc. Considering our requirement the best suited technique was pi/4 DQPSK. In this paper the design and analysis of DQPSK system is given by using ADS software.
