Abstract
This invention relates to decorrelation of signals in order to improve coding gains of wireless communications. To this end a branch signal processor includes a summer to determine a sum of a first branch signal and a second branch signal to produce a sum signal. A conjugate swapper to determine a conjugate swap of the first branch signal and a conjugate swap of the second branch signal to produce two swapped signals, wherein the conjugate swapper takes an imaginary part of the first branch signal to become a real part and a real part of the first branch signal to become an imaginary part of a new complex signal which new complex signal becomes a first swapped signal, and wherein the conjugate swapper takes an imaginary part of the second branch signal to become a real part and a real part of the second branch signal to become an imaginary part of a second complex signal which second complex signal becomes a second swapped signal. A differencer determines a difference of the first swapped branch signal and the second swapped branch signal to produce a difference signal and a diversity combiner configured to combine the sum signal, the first branch signal, the second branch signal a…
