Claim:
1. A fiber-wireless transmitting system comprising: a transmitter central office (CO), wherein a first lightwave is (i) modulated by transmitter data, and (ii) polarization multiplexed, to generate a PM-QAM modulated optical baseband signal; and a transmitter base station (BS) operatively coupled to the transmitter CO by an optical fiber, wherein, after obtaining the PM-QAM modulated optical baseband signal from the transmitter central office via the optical fiber, the PM-QAM modulated optical baseband signal is (i) heterodyned with a second lightwave, and (ii) up-converted to a PM-QAM modulated wireless signal; wherein the PM-QAM modulated wireless signal is at a mm-wave frequency of approximately f
