multi-carrier), which is a special case of frequency-division multiplexing. The MFSK receiver is based on energy detection, whereas DSSS and FRSS are coherent schemes equipped with an adaptive ...

Whereas fiber Bragg grating (FBG) sensors can be discriminated in the spectrum domain, through the popular wavelength-division-multiplexing (WDM) approach, Fabry-Perot interferometry (FPI) sensors ...
