Abstract
Prefilters for a receiver with multiple input branches are trained in the frequency domain. The frequency response B of a conditioned channel is determined without reference to the prefilters, and the frequency response W of the prefilters is computed from the frequency response B of the conditioned channel. The prefilters suppress interference.
