Abstract

A symbol vector received from a multiple antenna transmitting array is detected using a sphere decoder. The sphere decoder is used to select from a set of candidate binary strings that string which is most likely to have been transmitted. Soft information for use in a turbo decoder or the like is obtained by considering cost functions for a set of candidate strings, including strings derived from the most likely string by flipping one or more bits thereof.
