As efficient broad band interference, the matched spectrum interference is usually adopted in navigation counter measurements and anti-jamming tests. Currently, jamming effect comparisons between the matched spectrum interference and interferences with other modulations are often carried out. However, only its band and frequency are taken into consideration in these comparisons. Other parameters are...
Research on the waterway traffic flow modelling has been widely used in the formulation of waterway transportation regulations, navigation risk assessment, vessel traffic monitoring and organization. The fluency of one-way waterway transportation is proposed in this paper. By using the model, a simulation system is constructed on the basis of First Come First Served (FCFS) model. Monte Carlo simulations...
We investigate wavefront engineering of photon pairs generated through spontaneous parametric down conversion in lithium niobate-based nonlinear photonic crystals (NPCs). Due to the complexity of domain structures, it is more convenient to describe photon interaction based on the nonlinear Huygens–Fresnel principle than conventional quasiphase matching regime. Analytical expressions are obtained to...
To facilitate the engineers and technicians use the principles of selecting a reference system to query and calculation, to increase efficiency, improve the accuracy of calculation, we use VC and database technology to develop a query and calculation application program of principles of selecting a reference system. Users could get a series of data about principles of selecting a reference system...
A parameter adaptively adjustable utility function based on the asymmetric sigmoid function is investigated for the non-cooperative power control game (NPCG) model in cognitive radio networks (CRN). Each secondary user (SU) can adaptively adjust the parameter to track along with the wireless interference environment for the optimal power strategy. From the fairness of view, a pricing function related...
A non-cooperative joint rate and power control algorithm based on game model (NRPG) for wireless communication is formulated in this paper. It is shown that the proposed algorithm is well convergent with respect to the transmit power and rate and the Nash equilibrium solution (NES) for either the transmit rate or the transmit power is finally achieved. A pricing function that relates to both transmit...
