US 10,382,166 B1 · Constrained receiver parameter optimization

Abstract

Systems and methods are disclosed for constrained receiver parameter optimization. Two parameter optimization functions may be applied, with one function providing constraints on the results of the second function in order to determine a parameter set to apply in the receiver. A method may comprise determining a first parameter set based on a first function, determining a second parameter set based on a second function different from the first function, and determining a third parameter set by using the first parameter set to define a subset of a parameter space to which to limit values from the second parameter set. In certain embodiments, a least squares function may be used to constrain the results of a general cost function.
