摘要 |
Technical problem: In data transmission or transmission of redundancy-reduced signals, traffic flow and therefore required transmission capacity are not constant. State of the art: More or less intensive temporal utilisation of existing total capacity through the use of differing numbers of time slots in multiplex mode (TDMA, ATM) or through non-utilisation of residual time. Basic principle: Coded transmission and simultaneous use of differing numbers of codes which are orthogonal in relation to one another. Solution: Mixed CDMA-TDMA radio system. The number of channels (code division multiplex CDMA) assigned to an individual station is adjusted frame by frame on the basis of requirements in preceding frames. |
