发明名称 Code-modulated transmission process and transmission system operating according thereto
摘要 This transmission method serves to transmit information between a base station (BS) and a multiplicity of subscriber stations (MS) in transmission channels of a broadband signal. The transmission channels can be distinguished by different codes (Cs, C1, . . . , Cq) which modulate the broadband signal and which themselves are each modulated by the information to be transmitted in the respective transmission channel and are superimposed in the broadband signal. In this context, there is provision for at least one of the transmission channels (for example Cs) to be emphasized, as a prioritized transmission channel, in comparison with the other transmission channels (C1, . . . , Cq), in that its phase angle is shifted by a fixed amount in comparison with the phase angle of the other transmission channels.
