Abstract :
This paper compares different schemes that can be used to improve the performance of CDMA in wireless data systems. In particular, we consider a closed-loop power control scheme and an adaptive coding scheme. The comparison between these different techniques is performed in terms of mean transmission time and energy efficiency. Our aim is to show that an adaptive coding scheme can allow good performance with respect to typical power control techniques
