Studies on a new rapid hybrid acquisition system in MC-CDMA systems
Dezhou Zhang, Tongqing Wang · 2008
On the basis of the principle of the basic correlation property of PN sequence, a new rapid hybrid acquisition system is proposed in this paper, which is based on adaptive decision thresholds in MC-CDMA systems .The mathematics models and the detail performance analysis of this hybrid acquisition system are put forward in no fading AWGN channel and in Rayleigh fading channel. Computer simulations show the amelioration system proposed in this paper has a much shorter acquisition mean time than that of the basic scheme. So a conclusion may be drawn the amelioration scheme has a superior comprehensive synchronization performance to that of the basic scheme.
