Abstract :
A new suboptimal algorithm for detection of constant modulus signals in multiple-input multiple-output channels is presented. The deviation of the solution from the desired constant modulus property is used as a penalty or regularisation term in the conventional least squares cost function, and an iterative reweighted least squares procedure is used to minimise the regularised function.
