Pulse Duty Factor Evaluation of Indoor Direct Sequence Spread Spectrum Reliable Radio Communications
Masayuki Sakata, Tetsushi Ikegami (Meiji Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) In the spread spectrum (SS) radio communication, signals are normally spreaded by a SS code which is 100% duty ratio. This paper describes the communication performance evaluation of lower duty ratio SS code. In normal SS code, the error floor occurs at high signal to noise ratio because of the intersymbol interference caused by the delay waves in a multipath fading channel. However the low duty SS code improves communication performance because they avoid the intersymbol interference. In this study, ultra wide band (UWB) system and the indoor multipath fading environment are assumed. By the simulation, the improvements of the communication performance are confirmed.
