To produce digital baseband domain, it is important to consider the non-linear signals for linearization. We in this work have processed the second and fourth order linearization signals and processed the amplitude and phase. We used the modulate carrier second harmonic which is further utilized for amplifier transistor. We studied the effects of the proposed linearization method are evaluated on a single stage power amplifier for simulated QAM digitally modulated signal characterized with frequency spacing between spectral components up to 20 MHz for different input power levels.

Abstract In this work we have studied the Internet of Things and the possible smart grid functions that is supported by IoT. The intelligent real time applications such as real-time monitoring, control and system management are addressed with a smart substation. We found it that these application requires money. However, the Internet of Things have potential in the cost reduction that... In this work we have studied the Internet of Things and the possible smart grid functions that is supported by IoT. The intelligent real time applications such as real-time monitoring, control and system management are addressed with a smart substation. We found it that these application requires money. However, the Internet of Things have potential in the cost reduction that also help in cyber privacy and security. These issues also pose some challenges and only proper research can help to solve the issues. Read More Read Less

Abstract The vehicular navigation systems largely depend on GPS models. The major limitations of GPS receivers towards the course estimation are recognized as a low update rate (up to 10 Hz) and the impossibility to provide continuous navigation solutions in the periods of no signal reception. In this paper we have developed a model for the course estimation from GNSS and IMU... The vehicular navigation systems largely depend on GPS models. The major limitations of GPS receivers towards the course estimation are recognized as a low update rate (up to 10 Hz) and the impossibility to provide continuous navigation solutions in the periods of no signal reception. In this paper we have developed a model for the course estimation from GNSS and IMU systems and analysis of the IMU accuracy and behaviour during the dead reckoning situation. During experimentation we found that the IMU system accurately calculated the heading angle and found to be more effective. Read More Read Less
