In this paper, the design and experimental testing of a direct-sequence spread spectrum (DSSS) system for wireless indoor infrared network is presented. This method improves the wireless IR communications performances against multipath propagation and narrowband interference. We have implemented an IR-DSSS prototype with 100 MHz code frequency and about 6 Mbps bit rate. We also present some results on 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.
