The Optimized Threshold Decision of Pseudo Noise Code Acquisition in Spread Spectrum Communication

摘要

In this paper, the authors derived the distribu- tions of the probability of detection and of false alarm in func- tion of the decision threshold. An Optimized Threshold Decision (OTD) algorithm was proposed to decide the optimal threshold for reaching the best system performance in a given known chan- nel noise. By applying this OTD algorithm, the multiple access capacity can thus be maximized.
