Abstract

Reconfigurations of downlink dedicated channels are often necessary during call setup to eliminate code blocking encountered in 3G WCDMA systems. Orthogonal Variable Spreading Factor (OSVF) is the management scheme used to assign codes. Considering single code operation, the performance of a code selection scheme called Recursive Fewer Codes Blocked scheme (RFCB) has been studied. RFCB manages to mitigate code blocking and thus minimizes the fragmentation of the OVSF code tree capacity.
