Patent ID: 8139544

Claim:
A method comprising: receiving, at a receiving device, a first signal transmitted, from a first antenna, on a first communications path and a second signal transmitted, from a second antenna, on a second communications path, wherein the first signal includes a first set of data subcarriers and a first set of pilot subcarriers, and wherein the second signal includes a second set of data subcarriers and a second set of pilot subcarriers; separating the first set of data subcarriers from the second set of data subcarriers and separating the first set of pilot subcarriers from the second set of pilot subcarriers according to a signal separating function, wherein the signal separating function is based on a first channel estimate for the first communications path and a second channel estimate for the second communications path; and match-filter combining at least one pilot subcarrier of the first set of pilot subcarriers with at least one pilot subcarrier of the second set of pilot subcarriers.
