Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose chirp UWB system applied to industrial application. Reliability is highest demand for industrial applications, therefore, same high reliability and stability performance are also required in wireless communication systems for such applications. Since chirp scheme can be exploited stable communication performance under harsh multi-path communication environment, excellent performance is expected in the industrial scene where it is severe communication environment often we encounter.
However, in an employment of chirp scheme, symbol timing detection is often problem in receiver end. Therefore, in the proposed system, DS spread spectrum modulation is applied to its preamble. This enables establishing carrier synchronization without performing any carrier synchronization procedure.
Furthermore, in an employment of the proposed scheme, it enables very precise ranging and channel estimation function. This paper explains system configuration of the proposed scheme and evaluation results of its characteristics by computer simulations.
