Abstract :
We address the convergence model of a linear constant modulus (CM) linear array in the presence of noise and demonstrate how the constant modulus algorithm (CMA) performs for multiple signals in terms of the output amplitude. We also derive an expression to evaluate the signal strength of a CM canceler output and present the signal-to-interference ratio (SIR) at each stage CMA output assuming uncorrelated signals and infinite SNR at the first stage
