Abstract :
A framework for describing linearly constrained minimum variance (LCMV) beamforming structures is presented. The framework results from factoring the processor impulse response into a weight vector and a matrix which describes the structure. Classes of structures with equivalent steady-state and adaptive performance are discussed. Examples are given which illustrate application of this framework to several different structures.
