SIGNAL PROCESSING METHOD AND APPARATUS FOR COMPUTING AN OPTIMAL WEIGHT VECTOR OF AN ADPTIVE ANTENNA ARRAY SYSTEM

摘要

The present invention relates to a signal processing method of an adaptive array antenna system and apparatus. An object of the present invention is optimized for an array antenna system for providing a maximum gain with respect to a direction of the moving target signal source from an unknown data transmitted from the receiving side (or unpredictable) blind signal environment (blind signal environment) to provide an adaptive process to calculate the weight vector (weight vector). The final object of the present invention SINR: a useful way of using the optimal weight vector of the array system to maximize the (signal to interference + noise ratio the ratio of the signal-to-interference + noise) to improve communication quality and communication capacity is to provide. According to an aspect of the invention, the Lagrange jeseung technique is publishers from about 0 to handle most of the signal of the land mobile communication Messer having a digital signal processor (DSP) in real time according to the present invention (8N) (Note N is Fidelity modified such that the optimum weight vector calculated by the load calculation of the number Im) of the antenna elements of the array antenna. ; Jeseung Lagrange method, the adaptive array antenna system, the maximum eigenvalue, eigenvector, weight vector
