Implementation of a spread-spectrum-based smart lighting system on an embedded platform

In the last years smart lighting systems have attracted a lot of attention due to the increasing interest in reducing wasted power consumption. This work describes the implementation on an embedded platform of a smart lighting system, where the lamps communicate together creating a cooperative network, to trim the amount of light a given place. The proposed implementation relies on the spread spectrum technique and on optical orthogonal codes borrowed from optical communication research. Experimental results performed on a Freescale Freedom board, prove the feasibility of the proposed syste
