Abstract
A method for preventing a collision of an extended orthogonal code uses an extended orthogonal code applying a hadamard code, and prevents an extended orthogonal code's collision occurred by a duplicated address among a plurality of subscriber channels, in a wideband code division multiple access wireless local loop (WCDMA-WLL) communication system. The method effectively prevents an address collision among a plurality of channels in case that the channels having different data transmission speeds are simultaneously transmitted by using one WCDMA-WLL frequency. As a result, when a plurality of subscribers is divided by using an extended orthogonal code in a WCDMA-WLL system supporting a multiple-data transmission speed, the method prevents an allocation of a collidable matrix code. Also, the method prevents an error generated in dividing subscriber channels caused by a code collision, and thus enhances a reliability and a stability of a communication system.
