This PICBASIC complex LED matrix solution was developed by [Olivier de Broqueville] to drive a matrix of LEDs. Using some cheap transistors, common red LEDs, and a PIC16F628, he is able to drive a 6×6 ...
For high data rate wireless communications they use Orthogonal Frequency Division Multiplexing (OFDM) due to its high spectral efficiency and low computational complexity. It gives the architecture of ...
