Simple signature sequence adaptation through gain control

Research output: Contribution to conference › Paper › peer-review

Abstract

In this paper, we consider a new sequence adaptation scheme for direct sequence CDMA systems. In this new scheme, each user is given a number of signature sequences. The sequences, together with suitable gains applied, constitute an effective signature sequence for the user. The effective signature sequence can be changed adaptively by adjusting the gains applied to the component sequences. We consider different receivers, together with different gain control algorithms. Simulations show that with merely two sequences for each user, the performance of the system can be substantially improved.
