Simultaneous drone localization and communication using visible light

Drones that perform complex autonomous movements require a perfect estimate of their current position. However, internal measurement unit (IMU) errors introduce drift in this estimate, leading to significant discrepancies between the predicted and actual location. Various solutions have been proposed to calibrate the IMU, including methods...

Distribution of the electricitygrid of a tiny house community: Powerline communication

This thesis will discuss the design, simulations and measurements of a powerline communication system that utilizes FSK modulation in order to transfer information from a transmitter to a receiver at a baud rate of 1kbps, in order to reach the requirement of having an effective data rate of at least 6bps. This system is designed specifically to...

Low-SNR Operation of FSK Demodulators

This thesis introduces the concept of phase rotation cancellation (PRC) as a previously unknown error mechanism in narrow-band FSK systems, and proposes a new FSK demodulation algorithm to resolve PRC errors. Phase rotation cancellation is defined as an event where the signal phasor rotation in the IQ plane is temporarily cancelled by the...

Compressive Sampling for PPM and FSK Modulated Signals

Efficiency of the Analog to Digital Converters (ADCs) has always been an issue of concern, especially, when it comes to sampling wide band signals which require extremely high sampling rates. As the systems with wide band signals are gaining the front position in digital communications, the need to find ways to reduce the sampling rates of ADCs...
