UWB communication and networking systems with chaotic oscillator for low rate WPAN

This paper focused on the chaotic UWB (ultrawide band) systems for low rate WPAN. According to the UWB signal generation methods, there are three types of signals such as impulse, chaos, and chirp suggested by IEEE WPAN TG4a. The chaotic UWB signal generation has advantage of arbitrary wide band pulse shape. Based on chaotic signal, chaotic UWB communication systems are implemented, which is composed of RF blocks and digital blocks. And then they are interconnected as star topology with coordinator and several end nodes and shown the functions of image transferring.
