MULTICARRIER TRANSMISSION USING POLARIZED ANTENNAE
摘要
A system and method is provided for adaptive orthogonal frequency division multiplexed (OFDM) transmission (ADOT). The system and method includes OFDM processing of information symbols and is configured for transmission and reception of OFDM signals on orthogonally polarized antennas. Further, the system and method of the present invention is adaptable to channel conditions. An ADOT transmit system includes a transmit processor configured for a specific OFDM modulation of incoming data symbols to be transmitted based on channel condition data, and a pair or orthogonally polarized transmission antennas. An ADOT receive system includes a receive processor configured for restoring the transmitted OFDM signals according to a transmission mode employed in the transmit system. Continual measurement of the transmission channel yields channel condition data for use in selecting a particular transmission mode.
