Abstract:
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 (“CDM/CDMA”) and CDM/CDMA with second spreading factor codewords, wherein said second spreading factor codewords comprise a dynamic parameter determined from a required Signal-to-Interference Ratio of said VBR data stream and an amount of power remaining of a total power budget after power allocation to said CBR data stream.
