Abstract
The performance of an adaptive data rate transmission for uplink code-division multiple-access (CDMA) networks is analyzed where processing gain is adaptively changed according to the channel traffic density in order that a desired signal-to-interference ratio (SIR) can be achieved. The throughput of the adaptive rate system is asymptotically constant with respect to the proposed traffic density and is significantly improved compared to the fixed rate system. In addition, as the traffic density increases the adaptive rate system achieves almost linear increase in the channel delay, while that of the fixed rate system shows abrupt increase.
