SIGNAL SUBSPACE BASED METHOD FOR CALCULATION OF WEIGHT VECTORS

摘要

PURPOSE: A weight vector calculation method based on signal subspace is applied to a sensor array having a general signal sample or arbitrary structure. CONSTITUTION: A receiving data sample is prepared. A standard correlation sub-matrix is obtained from receiving data. Complex conjugate calculation is performed in the standard correlation sub-matrix. The standard correlation sub-matrix is disassembled to an orthogonal matrix and an upper triangular matrix. An N-th vector is obtained by using the upper triangular matrix. A weight vector is obtained by multiplying the orthogonal matrix and the N-th vector.
