Abstract
The DSSS technique is used in TTC system more and more.This paper di scusses the phenomenon of pseudo code error lock.And then on the basis of this, the influence of pseudo code error lock is analyzed aiming at the self-correlat ion properties and cross correlation properties of pseudo code.According to the cause of pseudo code error lock and its capture process,three measures of pseu do code error lock prevention are put forward,including improving self-correlat ion properties and cross correlation properties of pseudo code,power control te chnique and capture and tracking strategy In addition,these three measures are discussed in detail.关键词
