The objective of this project is to create a driver for a camera module (we used the OV7620). After taking the image with the camera, the driver will store into the external asynchronous RAM, and then send it to the computer through a serial cable
Many wireless communications channels consist of multiple signal paths from the
transmitter to receiver. This multiplicity of paths leads to a phenomenon known
as multipath fading. The multiple paths are caused by the presence of objects in the
physical environment that, through the mechanisms of propagation, alter the path of
radiated energy. These objects are referred to as scatterers. In the past, researchers
often looked at ways to mitigate multipath scattering, such as in diversity systems.
Multiple-input, multiple-output (MIMO) systems, on the other hand, use multipath
diversity to their advantage; a MIMO system has the ability to translate increased
spatial diversity into increased channel capacity.

Abstract: This article explores criteria necessary for reliable communication between electric vehicles (EVs) and electric vehicleservice equipment (EVSE). Data will demonstrate that a G3-PLC system has already met the criteria established by the automotiveand utility industries. Multiple international tests prove that a G3-PLC implementation is the optimal low-frequency solution.
