Implementing an Experimental Cognitive Radio System for DySPAN
2007
Motorola Labs implemented an experimental cognitive radio system for use at the Dynamic Spectrum Access Networks (DySPAN) Symposium 2007. To exercise a practical communication link in a shared spectrum, the system provided a live video feed via a dynamically-allocatable OFDM physical layer. Each demonstration unit included an RF signal conditioning module for DySPAN channel allocations, a custom RF transceiver IC, digital signal processing, and an embedded Linux operating system. Connected to the units via Ethernet, a PC presented a graphical user interface, including the video feed and visualization of the spectral sensing, signal detection, and frequency allocation that was taking place in the units.
