Adaptive schemes for packet data in a DS-CDMA environment

This paper presents a novel Adaptive DS-CDMA Slotted-ALOHA packet random access scheme for improving the throughput of the conventional DS-CDMA Slotted-ALOHA system. For this purpose a Mobile-assisted algorithm is envisaged to control the change of the transmission rate according to the traffic load. This algorithm revealed that the optimum behavior may be almost reached at a low complexity cost. Moreover, the proposed algorithm was found to be robust to intercell interference.
