Two or more of the generated plurality of weighted RF signals may be combined to form one or more combined RF signals. Each of the one or more combined RF signals may be processed by a different RF processing chain. The one or more output bit error rates of the receiver may be minimized by the generation of the plurality of RF weighting values.
