Performance Improvement in OVSF Based CDMA Networks Using Flexible Assignment of Data Calls

Davinder S Saini, Neeru Sharma
2011 International Journal of Computer Networks & Communications  
For same call reassignments are done to assign different codes at different times. The utilization of the code tree can reach close to 100%.  ...  Orthogonal variable spreading factor (OVSF) codes are used to support multimedia calls in CDMA wireless networks. The inefficient use of OVSF code tree reduces the system throughput.  ...  The multicode multirate compact assignment (MMCA) [12] is based on the concept of compact index, where the objective is to keep the remaining candidate codes in the most compact state after each code  ...
