Inter-satellite links provide direct connectivity between two or more satellites, thus eliminating the need for intermediate ground stations while sending data for various wireless applications. This paper proposes the investigations on performance evaluation of Radio Frequency (RF) signal at 60 GHz utilizing Matlab/Scilab computation. A block level model is designed at 60 GHz for estimation of satellite...
This research work addresses simulation results of a 2.4GHz Radio Frequency (RF) transceiver with Alternate Quadrature Differential Phase Shift Keying (AQ-DBPSK) modulation at 1 Mbps. The RF transmitter consists of an AQ-DBPSK modulator, an up conversion mixer, a 2.4 GHz Band pass filter and a power amplifier. At the receiver RF front end, the Low Noise Amplifier (LNA), mixer with down conversion...
The system level design and simulation results of an energy efficient 2.4 GHz Radio Frequency (RF) transmitter is being presented in this research paper. RF transmitter consisting of an Alternating Quadrature Differential Binary Phase Shift Keying (AQ-DBPSK) modulator, an up conversion mixer, band pass filter and a power amplifier are proposed in this work. The AQ-DBPSK technique is used as it increases...
Recent advances have resulted in the ability to integrate sensors, wireless communications and digital electronics into a single integrated circuit package. This capability is enabling networks comprised of very low cost sensors nodes that are able to communicate with each other. Energy efficient wireless communications is an essential requirement for Wireless Sensor Networks (WSN) in many environmental...
