Nonlinear Optics for Frequency-Doubling in Nanosatellite Laser Communication

Free-space optical communication attracts interest due to its promise of higher data rates for similar size, weight, and power costs compared with radio systems. However, while satellite-to-ground optical communication has been tested from low Earth orbit and the Moon, intersatellite optical links are still an area of active research and development. Second-harmonic generation (SHG, or “frequen...

Design and Simulation of an X Band LC VCO

In this paper, a systematic method for the circuit parameters design of a monolithic LC Voltage Controlled Oscillator (VCO) is reported. The method is based on the negative resistance generation technique. As a result, a VCO has been designed in 0.18um CMOS technology using a conventional VCO structure to obtain the optimum values for the phase noise and power consumption. The simulation result...

Design and Simulation of a Clamped-Clamped Micromechanical Beam AM Frequency Mixer-Filter

In the last decade Micromechanical components for communication applications has been fabricated via IC-compatible MEMS technologies. In fact, its most important impact is not at the component level, but rather at the system level, by offering alternative transceiver architectures that reduce power consumption and enhance performance. In this paper a mixer-filter for AM frequency receiver with ...

Message fragmentation assessment in DTN nanosatellite-based sensor networks

This paper proposes a proactive fragmentation mechanism for an optimal DTN message transfer. DTN message transfer is presented to give coverage to a terrestrial sensor network by using a nanosatellite communications link. Satellite communication is modeled with a multi-access mechanism with priority in downlink traffic (ALOHAGP). This new multiple access protocol is based on unslotted ALOHA ext...
