Patent ID: 8675784

Claim:
A method for detecting communications from a plurality of transmission antennas, comprising: receiving a signal, using at least one receive antenna, wherein the signal comprises data transmitted from at least one of the plurality of transmission antennas; calculating an equalized received signal and an equalized channel matrix using the signal and a channel matrix; determining whether a correlation factor threshold value is exceeded; and based on the act of determining, generating (1) a listed based log likelihood ratio (LLR) soft output based on an output from a sphere detector, or (2) a minimum mean square error (MMSE) LLR soft output based on the equalized received signal and the equalized channel matrix; wherein the act of generating comprises generating the listed based LLR soft output based on the output from the sphere detector if the correlation factor threshold value is exceeded, or generating the MMSE LLR soft output based on the equalized received signal and the equalized channel matrix if the correlation factor threshold value is not exceeded.
