RADIO TRANSMISSION SYSTEM AND METHOD AND TRANSMISSION STATION APPARATUS AND RECEPTION STATION APPARATUS USED IN THE RADIO TRANSMISSION SYSTEM |
摘要 |
<p>A radio transmission system is configured to, on the occasion of radio transmission of information between a transmitter and a receiver, perform the radio transmission of information using an orthogonal frequency and code division multiplexing transmission scheme of parallelly transmitting identical information by a plurality of sub-carriers. The radio transmission system has a spreading factor variable control transmitting device for parallelly converting information channel-coded at the transmitter, according to symbols transmitted simultaneously, and for spreading a sequence of parallelized symbols in at least one of a frequency direction and a time direction by a spreading code sequence of a designated spreading factor. <IMAGE></p> |
