Abstract
We examine the orthogonal variable spreading factor (OVSF) code tree management problem at the forward link of 3G WCDMA systems. Considering single code operation, we evaluate the performance of a code selection scheme called recursive fewer codes blocked scheme (RFCB). RFCB manages to mitigate code blocking and thus minimizes the fragmentation of the OVSF code tree capacity. Simulation results demonstrate the efficiency of the RFCB scheme compared to previously proposed schemes.
