—Quadratic constraints on the weight vector of an adaptive linearly constrained minimum power (LCMP) beam-former can improve robustness to pointing errors and to random perturbations in sensor parameters. In this paper, we propose a technique for implementing a quadratic inequality constraint with recursive least squares (RLS) updating. A variable diagonal(More)
—For code-division multiple access (CDMA) communication systems, many constrained linear receivers have been developed to suppress multiple access interference. The linearly constrained formulations are generally sensitive to multipath fading and other types of signal mismatch. In this paper, we develop robust linear receivers by exploring appropriate(More)
The problem of broadband range and bearing estimation is considered. It is demonstrated that the MUSIC technique can be implemented with an efficient search procedure, alternating maximization, for estimating range and bearing. Range-bearing estimation performance is compared via simulation to MVDR and to the Cramer-Rao lower bound. Experimental range(More)
