Performance_Analysis_of_PN_Code_Acquisition
文章中主要阐述了PN码的捕获,并对以前的各种捕获方法进行了改进。得出了基于FFT的快速捕获算法!(Abstract-A FFT-based parallel acquisition algorithm for Direct
Sequence/Spread Spectrum radio navigation system is studied to
solve long PN code acquisition using serial method. Frequency
domain analysis of FFT to acquire signal is applied in this paper
and state transfer function is used to derive the expression of
average acquisition time.)

OF,实际上OF是MCM Multi-CarrierModulation,多载波调制的一种。其主要思想是:将信道分成若干正交子信道,将高速数据信号转换成并行的低速子数据流,调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开,这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽,因此每个子信道上的可以看成平坦性衰落,从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分,信道均衡变得相对容易。在向B3G/4G演进的过程中,OFDM是关键的技术之一,可以结合分集,时空编码,干扰和信道间干扰抑制以及智能天线技术,最大限度的提高了系统性能。(OF)
