N2 - A chaos-based sequence generation method for reducing Multiple Access Interference (MAI) in Direct Sequence UWB Wireless-Sensor-Networks (WSNs) is presented, along with the schematic design in CMOS UMC130 1.2V technology of a modulator scheme, that takes into account both the transmitter and receiver antennas. Chaos-based spreading is numerically optimized to combine with the pulse profile (as obtained by extensive simulations) and maximizing the Bit-Rate (BR) at which each user may transmit given a certain link quality, measured as the Signal-to-Interference Ratio (SIR); when compared with traditional random sequences, the BR Increase is up to 30%. © 2007 IEEE.
