Adaptive Beamforming with LMS

In a traditional beamforming application, the goal is to design an antenna whose radiation pattern points in a specific direction instead of just being purely isotropic. This directionality can be used as spatial filtering and is achieved in many different ways. One way is to use a directional antenna, such as a dish whose directionality… Continue reading Adaptive Beamforming with LMS

Magnetic Communications

While playing with the magnetometer sensor on the Arduino for my DIY smart bike project I had an idea that I might be able to use a magnetometer as a crude communications receiver. The question being, Can we transmit data, by modulating a magnetic field, to a computer using a magnetometer sensor as a receiver,… Continue reading Magnetic Communications
