Abstract
A novel multiple access coding approach for mobile networked systems is presented based on complex quadraphase coding, matched error control coding and channel adaptation. This approach provides an adaptive multi-pleaccess communications capability where residual spreading gain, coding gain, data rates and channel loading are variables. Based on a blind estimate of the channel state, these parameters can be optimised to satisfy user Quality of Service Requirements. With these techniques, the foundation is laid for a new class of Collaboratively Coded Multiple Access Systems that can operate stand-alone or as hybrid CDMA/CCMA communications systems. A principal advantage of this approach is that high user and service density can be accommodated while the overall system complexity can be managed to tractable levels.
