Summary:The present disclosure provides a baseband unit, comprising a first electro-optic modulator and a second electro-optic modulator for modulating a baseband signal, the second electro-optic modulator being coupled to an input end of the first electro-optic modulator or to an output end of the first electro-optic modulator. The second electro-optic modulator is configured to receive a drive radio frequency signal, and to perform sub-carrier modulation according to the drive radio frequency signal. The present disclosure further provides an analog wireless fronthaul system and a signal processing method. La présente divulgation concerne une unité de bande de base comprenant un premier modulateur électro-optique et un second modulateur électro-optique permettant de moduler un signal de bande de base, le second modulateur électro-optique étant couplé à une extrémité d'entrée du premier modulateur électro-optique ou à une extrémité de sortie du premier modulateur électro-optique. Le second modulateur électro-optique
