Combining super exponential algorithm with logic strings and second order statistics for blind channel estimation

We combine the characteristics of the Super Exponential (SE) method with Logic Strings and Second Order Statistics (SOS) to blindly estimate a multipath channel. The estimator benefits from the good quality of estimation inherent of SOS methods to estimate the magnitude of a channel´s transfer function allied to the fact that the SE can estimate the channel phase response, and that Logic String estimator can resolve the remaining phase ambiguity inherent to SE and SOS estimators. It results in an estimator without any phase ambiguity with a better performance than the traditional SE method and without severe channel code restrictions as pure Logic String estimators.
