Description

ABSTRACT:
A method for obtaining a gain function by using an array of antennae and a weighting of the signals received or to be transmitted by vectors of complex coefficients. The complex coefficients are referred to as weighing vectors, according to which, a reference gain function being given, the reference gain function is projected orthogonally onto the sub-space of a gain function. The sub-space of the gain function is generated by the weighting vectors of the space of the gain functions. The weighting vectors of the space of the gain functions are provided in advance with a norm, and a weighing vector generating the reference gain function thus projected is chosen as the optimum weighting vector.
