| Outline of Final Research Achievements |
An Ultra-Wideband Impulse Radio (UWB-IR) sensor network system using Radio over Fiber technique has been proposed. In the proposed system, an optical signal processing technique using sampled fiber Bragg grating (FBG) effective for GHz wideband signals is applied to pulse shaping module. Numerical simulations showed that if the received signal amplitude at the antenna is 100 mV or more, the E/O converted optical signal can be directly shaped by the sampled FBGs with the peak reflectance of -15 dB. Bit error rate of On/Off keying (OOK) signal transmission is achieved to less than 10^-3. Also, in the experimental results, the OOK transmission using the signal generated by the sampled FBGs is achieved the target bit error rate of 10^-3.
