Based on optica carrier suppression, the 60 GHz optica-wire ess signa is generated by the 30 GHz oca osci ator in centra station ( CS) . The up conversion procedure a so take effect in CS, thus the oca osci ator is not needed in the base station ( BS) . The cost is cut down by this method. Thus the growing need of the high frequency te ecommunication can be met. A so, the simu ation system is set up to testify the t ransmission performance of the ROF signa .
