This paper proposes some novel techniques to accommodate users with different rate requirements in a Wideband CDMA system employing orthogonal variable spreading factor codes. Several static and dynamic code assignment strategies areput forth and their behavior investigated, in terms of call blocking probability and number of required reassignments. The efficiency they exhibit under various traffic profiles is demonstrated, quantitatively comparing their performance to some codeassignment schemes recently presented in literature.

Abstract
This paper proposes some novel techniques to accommodate users with different rate requirements in a Wideband CDMA system employing orthogonal variable spreading factor codes. Several static and dynamic code assignment strategies areput forth and their behavior investigated, in terms of call blocking probability and number of required reassignments. The efficiency they exhibit under various traffic profiles is demonstrated, quantitatively comparing their performance to some codeassignment schemes recently presented in literature.
