Abstract :
This paper studies the feasibility of the use of SAW devices in UWB systems, expected for the various kinds of sensing systems and short link wireless communication systems. We adopt complementary signal codes with chirp chips. We carry out simulation and basic experiment. The transmission signal produces high process gain characteristics and can handle multiple channels, which enables a real time high-speed operation along a relatively longer distance. We try to clarify a feasibility of the SAW devices and also discuss future works for SAW devices.
