The radio transmission system and the transmission bureau device and the reception bureau device which are used with method and that radio transmission system

摘要

Information the radio is transmitted at the time of, transmits identical information in parallel with the plural subcarriers using the orthogonal frequency mark divided multiplex transmission system which with transmission bureau and reception bureau, the radio transmission system which possesses the diffusion coefficient variable control transmission expedient where frequency direction and time direction spread at least on the one hand with spread mark series of the diffusion coefficient which series of the symbol which it converts in parallel according to the symbol which transmits the information which is encoded simultaneously in the radio transmission system which it tries to do the radio transmission of the above-mentioned information, at transmission bureau the channel, that is converted in parallel is indicated.
