High performance optical wireless communications
Abstract:
In this paper, the design and experimental testing of spread spectrum systems for wireless indoor infrared network is presented. Using these techniques improve the wireless IR communications performances against multipath propagation and narrowband interference. We have implemented both an IR-DSSS prototype with 100 MHz code frequency and 6 Mbps bit rate and low-speed IR-FHSS system for sensor interconnection. We also present some results about a simplified synchronization structure so as to be used on reduced-cost domestic equipment. These systems are suitable for different applications at low and medium rates, especially for In-house communications between domestic appliances or medical sensor interconnection.
