Performance of Coded Modulation employing

| Multilevel coding and bit{interleaved coded modulation employing diierential encoding and non{coherent reception over at fading channels are assessed. In order to achieve high bandwidth eeciencies mixed amplitude/phase modulation is performed. It is shown that multiple symbol detection only provides gains for multilevel coding as Gray labeling of the diierential symbols is not possible.

Electro-optic millimeter-wave harmonic downconversion and vector demodulation using cascaded phase modulation and optical filtering.

We describe and demonstrate an electro-optic technique to simultaneously downconvert and demodulate vector-modulated millimeter-wave signals. The system uses electro-optic phase modulation and optical filtering to perform harmonic downconversion of the RF signal to an intermediate frequency (IF) or to baseband. We demonstrate downconversion of RF signals between 7 and 70-GHz to IFs below 20-GHz...

Control of Three Phase Cascaded Multilevel Inverter Using Various Noval Pulse Width Modulation Techniques

In this paper, various novel pulse width modulation techniques are proposed, which can minimize the total harmonic distortion and enhances the output voltages from five level inverter to multilevel topologies. Multilevel inverters are important for power electronics applications such as flexible ac transmission systems, renewable energy sources, uninterruptible power supplies and active power f...

Large nonlinear phase modulation in quasi-phase-matched KTP waveguides as a result of cascaded second-order processes.

It has been known for many years that a nonlinear phase shift can occur with non-phase-matched second-harmonic generation in particular and with parametric processes in general.1·2 Frequently it is an undesirable factor that leads to instabilities in parametric oscillators. Such a nonlinear phase shift has been measured experimentally in bulk KTP at 1.06 11-m with Z-scan techniques, 3 which mea...
