Abstract
The present invention provides for a system to achieve a high data rate channel in a CDMA system. According to the preferred embodiment, multiple CDMA data sequences are modulated in parallel by multiple low data rate CDMA channels. Each low data rate CDMA channel digitally delays the CDMA data sequence modulated thereby by a different period of time, where the largest period of time of all the digital delays is less than one-half the period of a single chip of data. The high data rate CDMA channel is created by combining the output of multiple low data rate CDMA channels operating in parallel, thereby resulting in significantly increased data throughput.
