SYSTEM, TRANSMITTER, METHOD, AND COMPUTER PROGRAM PRODUCT FOR UTILIZING AN ADAPTIVE PREAMBLE SCHEME FOR MULTI-CARRIER COMMUNICATION SYSTEMS

摘要

A system, transmitter, method, and computer program product apply a performance improvement characteristic, such as phase rotation or power allocation, to both a known preamble and a data payload of a transmitted data packet, such that existing multi-carrier receivers are capable of decoding the data payload with the performance improvement characteristic applied. The performance improvement characteristic is applied by vector-matrix multiplication of the preamble and the data payload by the performance improvement characteristic.
