On Optimal PN Code Acquisition in CDMA Communications Environment : A Vector Space Approach

CDMA 환경하에서 최적화된 유사임의 코드 획득에 대한 연구 : 선형 공간적인 접근방법

Many of the currently used PN code acquisition algorithms detect the phase of the incoming PN signal on the basis of ML estimation principle and utilize statistics grounded in taking inner products. As an extension of PN code acquisition algorithm using one auxiliary code introduced by Salih in 1996, we propose a more and optimal (hardware / time / space complexity wise) algorithm by using a vector space approach. We outline some important differences between our algorithm and that introduced by Salih and in the process point out some advantages of our algorithm.
