SIGNATURE SERIES ALLOCATION METHOD OF CODE DIVISION MULTIPLE ACCESS(CDMA) SYSTEM

摘要

PURPOSE: A signature series allocation method is provided to minimize an interference between the users by using a new series. CONSTITUTION: A new series improves auto-correlation characteristic and cross-correlation characteristic, allocates a signature series to many users, and minimizes an interference between the users. When using the new series to CDMA system, a patching method is applied so that a signature series proper to the CDMA system is made and allocated. The patching method patches a rear part to a front part, and patches the front part to the rear part, by using the new series as a center line. Thereby, the interference between the users is not occurred, a system performance is more enhanced, and a system is easily embodied.
