Abstract
A wireless communication unit may receive a composite signal that includes data, a code division multiplexing (CDM) pilot sequence that is spread with a first channelization code, and a time division multiplexing (TDM) pilot sequence including a cyclic prefix. The TDM pilot sequence may be spread with a second channelization code. The composite signal may have a pre-defined portion of a time slot where the CDM pilot sequence is non-cyclic. The TDM pilot sequence may have a cyclic structure within the pre-defined portion of the time slot.
