Digital coherent combining (DCC) technique can increase the free space optical signal collection area by signals received an array of small apertures in a manner. To realize DCC different versions must be aligned phase digital alignment algorithm (PAA). Low computation complexity is imperative for PAA because main obstacle to implement and real-time manner availability processing (DSP) circuits offering very high gate density speed. In this paper we investigate relationship between...
In free space optical communication systems, multi-aperture coherent receivers based on digital beam combining (D-CBC) technique can provide exceptionally high sensitivity and are more robust to the atmosphere turbulence compared with single aperture same collection area. D-CBC relies phase alignment algorithm (PAA) align different versions of signals in phase. However, due limited working frequency signal processing (DSP) circuits, main obstacle realizing real-time multiple high-speed is...
Single-photodiode-per-polarization coherent receivers (SCRs) can preserve all of the merits conventional digital (DCRs) such as supporting chromatic dispersion (CD) compensation and polarization multiplexing, whilst have much lower optical complexity. But overall algorithm complexity SCRs is relatively higher because an extra dedicated field reconstruction (FRA) required in addition to standard algorithms used DCRs. The heavy computation burden introduced by FRA poses a major obstacle reduce...
High sensitivity, small size, light weight and low power are the most critical requirements for lasercom terminals used in free space optical communication (FSOC) systems. Coherent receivers have an exceptionally high sensitivity but their complexity consumption too high, especially space-borne terminals. Recently we propose a pseudo-single-side-band-signal based single-photodiode coherent receiver (P-SCR) with very algorithm which can potentially satisfy strict requirement of FSOC In this...
Free-space optical communication (FSOC) systems with variable data-rates can support different missions transmission distances and ensure reliable in periods of unfavorable weather conditions. The temporal diversity coherent combining (TDCC) technique adjust the data-rate a very large range using software-defined manner by taking advantage digital receivers able to recover signal field. In this paper, we investigate relationships between computational complexity, phase alignment error, loss...
In many power systems, especially in oil system, induction machine takes most part of the loads, which asks for continuous during operation. Now two-phase faults are usually made breakers three phase trip. A single-phase breaking method fault small current grounding system is proposed considering capacitor compensating. The voltage and under different locations analyzed, point also considered with accessing, based on an equivalent model. Finally, simulation model built PSCAD/EMTDC order to...
