主 题:direct sequence spread spectrum(DSSS) multiple access interference acquisition false alarm probability.
摘 要:For decreasing the multiple access interference of weaker signal acquisition in direct sequence spread spectrum(DSSS) systems,a new single decision algorithm is *** maximum value of correlation results is conventionally ***,there may be not only one strong peak among correlation results when the cross-correlation noise is strong enough to affect the correlation *** proposed algorithm decreases the false alarm probability through the decision of the ratio of the maximum value and the second maximum value of the correlation *** analysis and simulation results indicate that the proposed algorithm effectively suppresses the acquisition problem of multiple access interference in DSSS system.
