Abstract:We experimentally demonstrate a simple vector signal transmission
   architecture to realize the vector signal conversion from 8PSK to QPSK
   and optical carrier reuse based on radio over fiber system with fiber
   grating. A 5 GHz microwave carrying 1 Mbps 8PSK-vector signal is optical
   frequency doubled by employing double sideband carrier
   suppressed(DSB-CS) modulation scheme and up-converted to 10 GHz, optical
   carrier reuse is realized via a FBG in base station, and the finally
   demodulated vector signal is QPSK. As seen from optical spectra, we also
   generate a 50 GHz mm-wave signal. There is no additional laser source
   for the up-link data transmission and the cost is reduced.
