Abstract :
Spreading sequences are usually allocated to users irrespective of their channel conditions. In this paper we allocate sequences based on their channel conditions to improve the performance of the link model. We also propose an analytical model for the allocation scheme. We validate the analytical model on a down-link and evaluate its performance, to show an increased gain in the performance of the down-link model.
