It's easy to become bored spending time in airports. After all, you can do only so much work on a notebook computer with no reference material around. So, relax and have some fun at the airport–build ...

Abstract: Accurate displacement measurement with Doppler radar necessitates the incorporation of phase demodulation techniques. However, these techniques are prone to phase ambiguity, as target ...

Abstract: The vulnerable nature of satellite-based positioning systems under certain conditions such as urban canyons and indoors has given rise to the need for alternative positioning system.

This project implements a complete AM radio link on Xilinx FPGA hardware. It uses the Hilbert transform to generate analytic signals for envelope detection and demodulation, demonstrating practical ...

Block diagram of demodulator section: As you can see, I'm using a Costas Loop with a PI (Proportional-Integrator controller) to control the local oscillator The screenshot at the top shows an example ...
