SYSTEM AND METHOD OF SELECTIVELY COMMUNICATING USING OFDM TRANSMISSIONS AND SINGLE-CARRIER BLOCK TRANSMISSIONS

摘要

A data transmitter transmits data packets comprising a plurality of symbols. The data transmitter maps symbols in at least one of the data packets using a single-carrier transmission format, and maps symbols in at least another of the data packets using a multi-carrier transmission format. The data transmitter maps the symbols using the multi-carrier transmission format when the characteristics of a communication channel over which the data packets are transmitted satisfy a first set of conditions, and maps the symbols using the single-carrier transmission format when the data transmitter determines that the characteristics of the communication channel do not satisfy the first set of conditions. A receiver processes the data packets according to which transmission format was employed in transmission.
