COMMUNICATION SYSTEM, COMMUNICATION UNITS, AND METHOD FOR EMPLOYING A PILOT TRANSMISSION SCHEME

摘要

A composite signal may be generated with code division multiplexing (CDM) and time division multiplexing (TDM) pilots. A first pilot sequence may be a CDM pilot sequence. A second pilot sequence may have TDM pilot sequences including a cyclic prefix. The composite signal may have a cyclic prefix time domain portion based on the cyclic prefix and a base portion of the composite signal.
