Bidirectional carrier aggregation in next-generation radio-over-...

We have projected and verified a bidirectional intra-/inter-radio-access-technology carrier-aggregation method for a next-generation heterogeneous mobile network supported by filter bank multicarrier (FBMC). Successful transmission of intra/inter-band carrier aggregation between five broadband FBMC signals and three bands 4G long-term-evolution-advanced signal over 50?km single-mode fiber plus 10?m free-space is successfully broadcasted by employing an incoherent light-injection scheme in downli
