Non-coherent capacity bounds for the $M$ -ary differential chaos shift keying (DCSK) modulation system are derived and analyzed over multipath Rayleigh fading channels, deriving conditions on the channel state information/non-channel state information (CSI/NonCSI) and soft-decision/hard-decision (SD/HD), respectively. Meanwhile, the inter-symbol interference is modeled and analyzed mathematically...
This work proposes a novel amplitude modulation topology which including a recently discovered unique memory element — memristor. The circuit is validated by theoretical analyses and simulations that generating a standard amplitude modulation signal with no harmonic component. Our results support the feasibility that memristor can be applied to communication circuit.
Peak-shaving and valley-filling are important respects while making a scheduling plan, especially faced with the situation when Ultra-High Voltage (UHV) is introduced into the grid. With the target for calculating the cost and effectiveness of different peaking strategies continuously rather than only at the optimal point, this paper proposes an improved peaking model. The values of the objectives...
The common information model (CIM)/ extensive markup language (XML) was taken as the carrier to realize the mutual connection interface technology of isomerized electric power simulation software. This paper raised a kind of equal value electric power network model. The corresponding properties of classes in the model were expanded to save the CIM model element objectives, which overcame the shortcomings,...
With the fast development of the aerospace, the design and manufacture of landing gear are becoming hot topics nowadays. The development and application of the Virtual Prototyping Technology (VPT) have opened up a new field of the design and manufacture of the aircraft, the design, manufacture and test of the aircraft have made qualitative leaps in concept and method. Modeling and Simulation Techniques...
For rapid modeling and simulation of MEMS, a MEMS component library consisting of beam, anchor, plate and gap is developed with Modelica. The hierarchy structure of this library are proposed. In order to show micro component's structure, pin definitions, parameters and behaviors of mechanical beam are analyzed and then the lumped parameter beam is modeled based on object-oriented method with Modelica...
Jiangsu province, which has vast population and limited land, is facing with land resources shortage. However, the offshore radial sand banks provide huge potential land reserve resources. But, epeirogenic movement and the variation of elevation of the radial sand banks are quite frequent in coastal area of Jiangsu province; Hence, mastering law of the variation of elevation of the radial sand banks...
Rapid urban expansion in the surrounding area is a major reason of ecological environment deterioration. This research adopted SLEUTH model and imported the result of ecological environment analysis as the excluded layer by building multi-factor comprehensive decision model, therefore, realized a loose couple of urban growth model and ecological environment analysis. The result indicates that this...
