In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...

A simple serially concatenated turbo code using differential 8PSK modulation as the inner code and a [3,2,2] parity code as the outer code is studied. This inner code allows for noncoherent operation, but is decoded coherently according to turbo principles with iterative exchange of extrinsic probabilities. Results show a turbo cliff at 4.4 dB, about 1.5 dB away from the 8PSK channel capacity. ...

the determination of the optimal distribution of the catalytic activity profile, whichmaximizes the catalytic effectiveness, in created unsteady state conditions, is analyzed andtreated numerically for the case of a simple reaction. it was proven that the modulation, of thetemperature and the reactant concentration of the external bulk fluid, leads to a considerableincrease of the catalytic eff...

The supply of high data rates is a major goal of the communication industry. Towards this goal one solution is to use high level modulation combined with powerful coding. We propose a turbo-coded high-level modulation system (16/32/64-QAM) for the downlink that could be used for example in the future evolution of the EGPRS. The evaluation of such a system over the GSM channels is performed thro...

Next generation wireless networks must provide high broadband access, which can be achieved by combining the fiber optics and wireless technologies. In this paper we analyze a mm-wave radio over fiber (RoF) optical access network architecture, combining radio subcarrier multiplexing techniques to improve system efficiency with fiber dispersion mitigation provided by optical single sideband modu...
