Claim Text:
1. A method for optimally combining multi-path signals comprising: receiving a first signal that traveled a first path from a transmitter to a receiving location, wherein the first signal contains signal data and has a first distortion; receiving a second signal that traveled a second path from the transmitter to the receiving location, wherein the second path is different than the first path, and wherein the second signal contains the same signal data and has a second distortion that is different than the first distortion; maintaining noise power from the first and second distortions constant; adaptively generating according to an objective function a first weight value prior to a filter and adaptively generating according to the objective function a second weight value prior to the filter; applying the first weight value to the first signal to produce a first weighted signal with a first degradation; applying the second weight value to the second signal to produce a second weighted signal with a second degradation; running a stochastic adaption algorithm based on a set of norms that are defined independently from the first and second weighted signals; linearly combining the first weighted signal and the second weighted signal to produce a combined signal with a combined signal degradation to increase the combined signal in a combined signal to noise ratio (SNR), wherein the combined signal degradation is less than the first degradation and the combined signal degradation is less than the second degradation; and driving the first and second weighted signals towards a match by minimizing a value of the first weighted signal less the second weighted signal.
