Improved method for improving stability property of communication system

InactiveCN102710363AReliable and confidential optimal transmission power valueGuaranteed stabilityError preventionSecret communicationCommunications systemSlack variable
The invention discloses an improved method for improving the stability property of a communication system, belonging to the technical field of communication. The improved method comprises the steps of: determining a parameter, a determining an optimization program, simplifying the optimization problem, introducing a slack variable, transforming a half-infinite limit condition into a linear matrix inequality, obtaining a final form of the optimization problem, proving that the solution is an optimal solution, solving an optimal sending power popt, and outputting the optimal sending power popt. According to the improved method, on the premise of considering that the channel state information of a wiretap channel is not completely known, an optimal scheme is re-designed, therefore, the stability property of secret communication is improved. Under the condition of realizing that the state information of the wiretap channel is not completely known, a manual noise covariance matrix and a transmission beam forming vector are combined for optimization design, thus the stability of the secret communication is improved. Compared with the condition of known channel state information, the improved method has remarkable advantages on the stability of the whole system.

Method and system for generating a real time bill of materials and evaluating network performance

An automated method for quickly generating a complete bill of materials and total cost information in real time. Components for a desired system are specified and / or replaced by substitute components, while continuously predicting the wireless system performance. A design engineer builds a model of the desired wireless communications system and specifies each component necessary to provide sufficient or optimal system performance. A parts list is maintained, in real time, that contains a definition of each system component and its associated performance and cost parameters. As the user changes wireless system designs through a series of "what-if" scenarios, components are replaced with substitute components, cable lengths are modified, antenna systems and base station parameters are re-designed and moved to alternate locations, etc. The bill of materials is automatically updated and component costs and total system costs are immediately available to the design engineer. The designer may choose to swap components for less expensive components or may investigate several alternate radio frequency distribution and antenna schemes, etc. The performance characteristics of the system are automatically updated as is the system cost as the designer to assesses the trade-offs between performance and cost at the same time.

Bus stop site selection and layout optimization method based on passenger trip spatial distribution

The invention mainly provides a bus stop site selection and layout optimization method based on passenger trip spatial distribution. The bus stop site selection and layout optimization method based on the passenger trip spatial distribution mainly comprises construction of a bus stop site selection optimization model and a solution algorithm thereof. The bus stop site selection optimization model takes minimization of walking distance of all the residents for taking buses as a goal and considers realistic constraint factors such as maximum walking distance between a resident dense point and a bus stop and upper and lower bounds of distance between adjacent stops, the solution algorithm of the bus stop site selection optimization model is a novel hybrid algorithm and combines advantages of a bacterial foraging optimization algorithm and a group random search algorithm, and according to problem characteristics, individual bacterium coding, initial bacterial colony generating, individual bacterium evaluation function generating and bacterial foraging operations are redesigned. The bus stop site selection and layout optimization method based on the passenger trip spatial distribution scientifically and reasonably determines bus stop positions by combining a real road topological structure according to trip spatial distribution characteristics of residents nearby a route, so that resident trips are facilitated, and bus operation efficiency is also improved.

A cooling process integration method for accelerating a laminar cooling device belongs to the technology field of steel plate laminar cooling. The process includes the following steps: establishing a function of the water ratio between upper and lower collectors, which varies with the flow rate and the thickness: F ratio is equal to f (thickness, Top-flow); redesigning the KTS2 value which ranges from 1 to 9 of the seventh bit in the self-adaption program segment of the ACC secondary automation model program; figuring out the distance from the head part of the steel plate to the center line of the rolling mill based on the roller table speed and the moving time of the steel plate on the roller table; and screening the unstable PDI date sent in the pony-roughing pass by the PDI data sent to the ACC steel plate only in the last pass through modifying the triggering condition of the pre-computation in the ACC automation control system; meanwhile, receiving only the PDI data of the steel plate in the last pass and pre-computation without comparing the two PDI data of the same steel plate by ACC; and moreover, reducing the starting conditions of the ACC automation cooling so as to solve the problem that the steel plate fails to cool due to inability to meet all the conditions.
