Adaptive free-space optical (FSO) communication links have been extensively studied in order to adapt variable atmospheric channel environments due factors such as turbulence. As a supporting technology, an all-in-one BPSK/QPSK switchable transmission and reception method is proposed experimentally demonstrated for adaptive modulation format switching FSO links. The of both formats are realized based on the same IQ modulator single-photodetector coherent receiver. Simulation experimental...
A new circular shape patch ultrawideband (UWB) single feed microstrip antenna is described in this paper.The radiated of the proposed UWB embedded with slots to improve radiation characteristics ensuring a wide impedance bandwidth.In ground plane, two rectangular rings are etched provide proper matching over frequency range.The layer overall dimensions 55 mm by 56 fabricated using low cost 4.3 relative permittivity FR-4 substrate.From results obtained, can an bandwidth ranging from 2.2 GHz...
A new, to our knowledge, simultaneous bi-directional all-optical multipoint-to-multipoint switching scheme is proposed and experimentally demonstrated for free-space optical (FSO) communication networks. Through tuning the switch at core node, link between each two arbitrary remote nodes can be established. The multipoint transmission performance tested in a turbulence-tunable atmospheric cell using 6.25 Gbit/s quadrature phase-shift keying (QPSK) signal. At bit error rate (BER) of 1×10 −3 ,...
