Abstract
A method and apparatus for pilot signal transmission is disclosed herein. In particular, a pilot transmission scheme is utilized where pilot sub-carrier bandwidth differs from data sub-carrier bandwidth. Because some user's data sub-carriers will no longer have the user's pilot sub-carriers adjacent to them, the set, or pattern of sub-carriers used by the pilot blocks changes at least once in a burst. Changing the pilot block pattern (the set of occupied pilot block sub-carriers) at least once in the burst serves to increase the frequency proximity of occupied data sub-carriers to occupied pilot sub-carriers in the burst.
