AB - <p>The convergence behavior of the Least Squares Constant Modulus Algorithm in an adaptive beam forming application is<br>examined. It is assumed that the desired signal and the interferÂ¬ence are uncorrelated. The improvement in output SIR with<br>each iteration of the algorithm is predicted for several different signal environments. Deterministic results are presented for an<br>environment containing two complex sinusoids. Probabilistic results are presented for a constant modulus desired signal with a<br>constant modulus interferer and with a Gaussian interferer. The asymptotic improvement in output SIR as the output SIR becomes<br>high is also derived. The results of Monte Carlo simulations using sinusoidal, FM, and QPSK signals are included to support the<br>derivations.</p>
