Simulation of FBG sensing networks using CDM + SDM

To increase the multiplying density of FBG sensors, a novel FBG sensing network using CDM + SDM by coding measuring points directly is proposed, which increases the multiplying density greatly and is easy to implement in engineering for its simple structure. Simulation of an example using (25,3,1)-OOC code indicates that although the system's multiplying density increased greatly, its measuring precision decreased.
