摘要
PURPOSE: A method for avoiding extended orthogonal code collision in a WCDMA-WLL(Wideband CDMA-Wireless Local Loop) is provided, which transmit data of each subscribe without error by preventing a collision between subscriber channels. CONSTITUTION: According to the method, an initial value of a variable K indicating a degree of a matrix of an extended orthogonal code is set as "1"(S11). An extended degree N of the extended orthogonal code is checked(S22). After checking a multiple M of a data transmission rate, a range of a variable L is set(S33). The Kth matrix code of the extended orthogonal code is allocated(S44). It is checked whether the allocated matrix code is a matrix code in being used at present or a matrix code deleted from a matrix code list(S55,S66). If the allocated is neither used nor deleted, the £(Lx N)/M+K|th matrix code is deleted from the matrix code list(S77). And it is judged whether there is a matrix code request requiring other matrix code(S88).
