Abstract

Orthogonal variable spreading factor (OVSF) codes always suffer from code blocking. Low rate users further add to this limitation to create code blocking for high rate users. The paper proposes a fair multi code design to provide fairness to different rate users in 3G and 4G traffic. The code availability for new call depends upon the current status of the code tree which makes the design adaptive to traffic conditions. Simulation results are demonstrated to show the superiority of the proposed design as compared to the existing schemes.
