Abstract:
A system for providing a high data rate code-division multiple access (CDMA) channel, comprising:a plurality of low data rate CDMA channels acting in parallel;a plurality of unique digital delays, each unique digital delay being associated with one of the plurality of low data rate CDMA channels and being a unique time portion of a chip period, the unique digital delays delaying a CDMA data sequence modulated by the associated low data rate CDMA channel by a predetermined amount of time, where the unique digital delays are calculated by ##EQU1##where M is the number of the channel, and N is the total number of CDMA channels, and C is the chip period; anda transmitter which transmits the sum of the CDMA data sequences as a high data rate CDMA channel.
