Integrating power control, error correction coding, and scheduling for a CDMA downlink system.

Transmitting multimedia data over a code-division multiple access (CDMA) channel presents a new set of challenges: data demands will sometimes exceed the system capacity, in which case the system must make the most efficient use of its limited resources. In this paper, we present our approach for un...
