Abstract
Bilinear methods for jointly estimating the channel coefficients and the symbols emitted through these channels are very appealing. However, they can be trapped by local minima. This paper provides: (i) a full characterization of the local minima, (ii) a simple criterion for checking whether the procedure has converged to the global minimum, (iii) a simple algorithm for obtaining this solution, with a proof of convergence
