Management of Channelization Codes of WCDMA
نویسندگان
چکیده
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.

Comparison of code reservation schemes at the forward link in WCDMA
We examine resource reservation schemes for the management of orthogonal variable spreading factor (OVSF) codes at the forward link of 3G mobile communications systems employing WCDMA. Like in every multiservice network, different rate calls in 3G systems will perceive dissimilar system performance if no measures are taken and the channelization code tree is treated as a common pool of resource...
متن کاملPerformance Analysis and Allocation Strategy for the WCDMA Second Scrambling Code
The WCDMA downlink is limited by Node-B cell power and the number of channelization codes. With upcoming capacity enhancement techniques, like MIMO and HSDPA, the potential limitation in channelization codes becomes visible more frequently. The WCDMA standard allows for allocation of traffic on a secondary scrambling code, which is non-orthogonal to the primary scrambling code. This paper analy...
متن کاملNon-blocking OVSF codes and enhancing network capacity for 3G wireless and beyond systems
Orthogonal variable spreading factor (OVSF) codes are employed as channelization codes in WCDMA. Any two OVSF codes are orthogonal if and only if one of them is not a parent code of the other. Therefore, when an OVSF code is assigned, it blocks all of its ancestor and descendant codes from assignment because they are not orthogonal to each other. Unfortunately, this code blocking problem of OVS...

We examine the problem of assigning and reassigning orthogonal variable spreading factor (OVSF) codes at the forward link in 3G mobile communications systems employing WCDMA. Efficient channelization code management results in high code utilization and increased system capacity. We introduce a new code selection scheme, which, by means of a very simple measure, attempts to mitigate the problem ...
متن کاملAn Efficient Dynamic Orthogonal Variable Spreading Factor Code Allocation Approach in WCDMA through Modified Adaptive Genetic Algorithm
Orthogonal Variable Spreading Factor (OVSF) codes would give variable data rate transmissions for different bandwidth supplies in Wideband CDMA (WCDMA) networks. These OVSF codes are used for the channelization of codes in WCDMA. In WCDMA, effective utilization of OVSF codes has become an active area of research as the number of codes is very limited. It is a fact that the successor and predece...
