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.

Abstract: A system and method for multiple rank modulation transmission in a Multiple-Input Multiple-Output (MIMO) or Multiple-Input Single-Output (MISO) system is provided. The method includes receiving at a transmitter, a signal with a plurality of bits and separating the received signal into a rank index bit block and a signal modulation bit block. The signal modulation bit block is encoded in a signal modulation scheme for transmission. The rank index bit block is used to select a rank to be activated, wherein the activated rank contains at least one active transmitter antenna and the encoded signal modulation bit block is transmitted via the activated rank being at least one activated transmitter antenna. The transmitted encoded signal modulation bit block is received via the receive antenna and a receiver a rank index and a transmitted symbol estimated from the received signal. The signal modulation bit block is finally decoded.
