Parameter Analysis of Spread-Spectrum Sequence Acquisition in P-SCDMA System
Song Liu · Journal of Chongqing University of Posts and Telecommunications · 2002
Based on the spread spectrum code acquisition scheme of P SCDMA (Packet Switch Synchronous Code Division Multiple Access), the paper sets up a signal model by adopting I Q matched filter and theoretically analyzes parameters of the acquisition system with the statistical result of general acquisition probability and minimum acquisition time in the system. Figures of false alarm probability versus EC/NO and detection probability versus EC/NO are presented and the results under different conditions are obtained. This method of analysis on I Q matched filter can also be used in any other fast acquisition system, such as in IS 95.
