During data transmission or transmission of redundancy-reduced signals, the traffic volume and, hence, the necessary transmission capacity are not constant. Instead of the prior art approach of more or less intensive use of the total capacity, the basic idea of the invention is coded transmission and simultaneous use of more or less many, mutually orthogonal codes. An embodiment shows the use of a mixed code-division multiplex (CDMA)-time division multiplex (TDMA) radio system. The number of channels assigned to a signal station (CDMA) is determined anew frame-by-frame (TDMA) in response to requests in preceding frames. |
