Title: Diversity combining in a communications system

Abstract: A diversity path signal combiner includes two orthogonalizers which produce, from two received signals, two sets each of two relatively orthogonalized signals. One orthogonalized signal of each set includes one of the two received signals multiplied by a normalization factor, and the other includes a signal derived from both of the received signals, multiplied by a normalization factor. The inputs to the two orthogonalizers are relatively interchanged. Two signal combiners adaptively combine the two sets of orthogonalized signals with respective weights, and a selector selects between the resulting combined signals to produce an output combined signal.
