@article{Shirzad_Poorahmadazar_Ghobadi_Nourinia_2019, title={Evaluation of the Constant Modulus Algorithm Application}, volume={4}, url={https://ijnes.org/index.php/ijnes/article/view/508}, abstractNote={<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>}, number={1}, journal={International Journal of Natural and Engineering Sciences}, author={Shirzad, H. and Poorahmadazar, J. and Ghobadi, Ch. and Nourinia, J.}, year={2019}, month={Jul.}, pages={81â€“93} }
