This method improves the wireless IR communications performances against multipath propagation and narrowband interference. We have implemented a IR-DSSS prototype with 100 MHz code frequency and 6 Mbps bit rate. We have also studied the effects of both Gaussian and sinusoidal signal conformation over wireless optical DSSS systems. These results show that these techniques reduce the adjacent-channel interference without loss of process gain or substantial reductions of BER vs. S/N performances. We also present some results about a simplified synchronization structure to be used on reduced-cost domestic equipment. These systems are suitable for different applications at low and medium rates, especially for in-house.||URI:||http://hdl.handle.net/10553/46866||ISSN:||0098-3063||DOI:||10.1109/TCE.2004.1309412||Source:||IEEE Transactions on Consumer Electronics[ISSN 0098-3063],v. 50, p. 484-490|
