1. A method of communicating Constant Bit Rate (“

  • CBR”

    ) data and Variable Burst Rate (“

    VBR”

    ) data in a single RF carrier via a communication system, said method comprising the steps of;

    determining whether the data stream is CBR or VBR;

    when said data stream is CBR, communicating the CBR data stream using Code Division Multiplexing/Code Division Multiple Access (“

    CDM/CDMA”

    ) with first spreading factor codewords, whereby a CBR-CDMA data signal is generated; and

    when said data stream is VBR data, communicating the VBR data stream using Time Division Multiplexing/Time Division Multiple Access (“

    TDM/TDMA”

    ) and CDM/CDMA with second spreading factor codewords.
