Comparison of Double-Sideband and two-Single-Sideband Systems
We compare a Double-Sideband (DSB) system with 4 IFs of 2-GHz bandwidth each (4 GHz times two polarizations = 8 GHz total) and the two-Single-Sideband (2SB) system with 8 IFs of 2-GHz bandwidth each (4 GHz times two polarizations times separated two sidebands = 16 GHz total) that has been proposed for the baseline ALMA. We compare the sensitivity of these systems by adopting the state-of-art re...
متن کاملDemonstration of Electrical Dispersion Compensation of Single Sideband Optical Transmission
We describe a demonstration of electrical chromatic dispersion compensation of 10 Gb/s single sideband optical signals. Eye-opening and bit error rates of less than 10 were achieved after compensation of -2040 ps/nm, equivalent to 120km of non-dispersion-shifted fibre and beyond the dispersion limit for 10Gb/s. A passive sideband filter was used to produce the single sideband signal, a techniqu...
متن کاملImage-Reject and Single-Sideband Mixers
Image-reject mixers (IRMs) and single-sideband mixers (SSMs) play a key role in many of today’s microwave and rf systems [1, 2, 3]. IRMs and SSMs reduce system cost and complexity by removing the need for expensive preselection, and one or more stages of upor downconversion. IRMs simplify downconversion by employing phase-cancellation techniques to separate the downconverted products resulting ...
متن کاملPacket Scheduling Algorithms for Interconnected Single-hop Multichannel Systems
In this thesis, we investigated some aspects of the packet scheduling problem for networks of single-hop multichannel systems. We described typical single-hop multicannel systems, i.e. the telecommunication satellite ones, with more attention to satellite constellations using intersatellite links. This kind of system is the main subject of this thesis. We described also other systems, again cla...
متن کاملPhase-coherent orthogonally polarized optical single sideband modulation with arbitrarily tunable optical carrier-to-sideband ratio.
We propose and experimentally verify a novel approach to achieve phase-coherence orthogonally polarized optical single sideband (OSSB) modulation with a tunable optically carrier-to-sideband ratio (OCSR). In our scheme, the orthogonally polarized OSSB signal is achieved using a dual-polarization quadrature phase shift keying (DP-QPSK) modulator without an optical band-pass filter (OBPF). Theref...
