摘要：

A chaos-based sequence generation method for reducing multiple access interference in direct sequence ultra-wide-band wireless-sensor networks (WSNs) is presented. With this it is possible to increase the expected bit rate (BR) at which each user may transmit given a certain link quality, measured as the signal-to-interference ratio. When compared with traditional random sequences, chaos-based spreading results in a BR increase of up to 20%.
