OVSF CODE SYSTEM AND METHODS

摘要

A code indexing method for orthogonal variable spreading factor codes (OVSF) introduces a single number mapped to each code. The new code number itself n ot only provides the code signature, but it is also used for the OVSF code generation. In addition, it provides easy and fast generation of the availab le code list without the help of look-up table. This capability improves the dynamic code assignment.
