Orthogonal variable spread-spectrum factor code tree state storing, distributing and releasing method and device

The invention provides a method for storing the condition of variable spread-spectrum factor code tree, comprising following steps: distributing several storage units for individually storing the condition of leafage nodes of variable spread-spectrum factor code tree; initializing said storage units into available condition; when distributing one code of variable spread-spectrum code tree, arranging the storage units relative to all leafage nodes of said distributed code into the unavailable condition; and when releasing one code, arranging the storage units relative to all leafage nodes of said released code into available condition. The invention also provides a method for distributing and releasing the variable spread-spectrum code based on said storage method and the relative method. The inventive method and device can effectively utilize the storage space, simplify the operation process, reduce the processing complex and accelerate the process of distributing and releasing the variable spread-spectrum factor code.
