Absir-mi -In this paper we consider the application of some adaptive algorithms for the antenna array beam steering. Three spatial channel models ( Lee's Model, Gaussian Angle of Arrival Model and Discrete Uniform Distribution Angle of Arrival Model) and 12 -element antenna array are simulated. The antenna array beam steering is performed by using the adaptive algorithms: Least Mean Sgziare -LMS, Least Mean Fourth -LMF, Recursive Least Square -RLS and Sample Matrix Inversion -SMZ. The output antenna array SNIR is analyzed and plotted relating to the angular width and the iteration number the adaptive algorithms.

Designing an integrated telecommunications and computer network using a simulation model requires defining all the network and communication elements that make up the network and network communication. The accuracy, quality, and usability of the simulation results depend on the accuracy and the way of defining the network traffic as a timed event between the source and the destination in the network. In this paper, the method for a more accurate definition of network traffic required for the development of a simulation model using the software tool OPNET is proposed. Network traffic can be represented using a multigraph associated with an appropriate matrix of network traffic over time. Time definition of network traffic is enabled by applying the method of sampling multigraphs with the mathematical derivation of the corresponding statistical distribution function. Predicted or existing communication in the network describes using the derived function of network traffic distribution and precisely defines the OPNET simulation model.
