We propose a full-duplex millimeter-wave fiber-radio network for providing wireless customer access to broadband services. It consists of a hybrid star-tree architecture connecting remote antenna base stations to a central control office (CO) by incorporating wavelength-division multiplexing (WDM) of the optical signals and subcarrier multiplexing (SCM) of… (More)
A spectrally efficient millimeter-wave (mm-wave) fiber-wireless transmission system is presented demonstrating downstream transportation of 155-Mb/s BPSK data at 38 GHz over 50 km of standard single-mode fiber and a 5-m wireless link. The effect of fiber chromatic dispersion on the transmission of the mm-wave optical carrier was overcome by using a single… (More)
A high capacity full-duplex millimeter-wave fiber-radio network which incorporates remote up and downconversion is demonstrated. This technique minimizes fiber dispersion-induced phase noise, allowing higher-order modulation formats to be incorporated which increase network capacity and spectral efficiency. Remote up and downconversion also enables lower… (More)
We demonstrate a novel and simple technique for the generation of optical SSB with carrier using a single Mach-Zehnder modulator to overcome dispersion effects in fibre-wireless systems. A dispersion penalty <0.5 dB for BER of 10/sup -9/ was measured for 51.8 Mb/s BPSK data transmission at 12 GHz over 80 km of fibre.
Data transmission in a mm-wave optical link incorporating optical SSB modulation via a dual-electrode modulator, has been modeled. Simulations of received eye-diagrams show that the SSB generator is tolerant to errors in phase and power level of the drive signals: /spl plusmn/5/spl deg/ and 3 dB respectively.
We investigate the impact of fiber chromatic dispersion on the performance of an externally modulated millimeter-wave fiber-radio system incorporating a broadband radio direct-sequence code division multiple access Ž . DS-CDMA scheme. In particular, we investigate the effect of dispersion on DS-CDMA signals with regard to CDMA code rate, center frequency,… (More)
A broadband integrated photonic-antenna interface is presented that is suitable for application in multiple millimeter-wave fiber-wireless service applications. The antenna base-station module is based on hybrid integrated circuit technology and operates over the entire Ka-band (26 - 40 GHz).
We investigate experimentally and theoretically the transmission of multi-channel millimeter-wave CDMA signals in a fiber-radio system. The use of optical SSB modulation enables transparency of the optical link to CDMA signal propagation, while channel crosstalk is due to the CDMA codes.
