Dans le système radio cellulaire de troisième génération, un facteur d'étalement variable (VSF) et des schémas multi-codes (MC) sont adoptés pour prendre en charge la transmission de données à plusieurs débits. Bien que ces schémas affectent les statistiques d’interférence intercellulaire et donc l’efficacité spectrale, leur impact précis n’est pas complètement compris. Dans cette lettre, une solution de forme fermée pour les moments d'interférence intercellulaire de liaison inverse est dérivée et l'efficacité spectrale est calculée à partir de la solution. Il est démontré que l'interférence intercellulaire a un effet néfaste sur l'efficacité spectrale à mesure que la proportion d'utilisateurs à haut débit dans une cellule augmente.

Abstract: In the third generation cellular radio system, a variable spreading factor (VSF) and a multi-code (MC) schemes are adopted to support multirate data transmission. Although these schemes affect the statistics of intercell interference and therefore the spectral efficiency, their precise impact is not completely understood. In this letter, a closed-form solution for the moments of the reverse link intercell interference is derived and the spectral efficiency is calculated from the solution. It is shown that the intercell interference gives a bad effect to the spectral efficiency as the portion of high rate user in a cell is increased.
