Abstract
The authors propose an efficient and computationally fast algorithm for solving the mix-up problem in complex arrays. The Lagrange multiplier theory is used in the optimisation of the constant modulus algorithm (CMA) cost function and the input data are processed in blocks. Furthermore, a simplification of the CMA cost function is proposed that leads to a robust algorithm for solving this problem. Simulations are presented to support the analysis
