Communication system, communication units, and method for employing a pilot transmission scheme

摘要

A method of pilot-assisted data communication comprises transmitting a composite signal. The composite signal comprises data, a first pilot sequence with non-cyclic properties; and a second pilot sequence, such that the composite signal within a designated or pre-defined time region of one or more time slots exhibits a cyclic prefixed time domain structure. Both the first pilot sequence and second pilot sequence are transmitted in substantially this same designated or pre-defined time region in one or more time slots.
