Description: 由于信号进行多径传播达到接收点处的场强来自不同传播的路径，各条路径延时时间是不同的，而各个方向分量波的叠加，又产生了驻波场强，从而形成信号快衰落称为瑞利衰落。-Because the signal carries on the multipath propagation to achieve the point of reception place field intensity from the different dissemination way, each way delay time is different, but each direction component wave superimposition, also has had the standing wave field intensity, thus forms the signal quick decline to be called Rayleigh to decline.

Description: 为了克服原有抗多径算法在偏移二进制载波( BOC)信号上性能不如粗捕码( coar se/ acquisition co de, C/ A 码)的缺点, 并消除 BOC信号在跟踪时特有的多峰模糊特性, 将一种
新的参考码应用在 BOC信号的跟踪中,并与窄相关器以及高分辨相关器( HRC)技术进行了比较, 分别给出了多径误差包络, 从仿真结果中得出了最佳参考码码型,并根据最佳参考码
分析了成形( Shaping) 相关器的噪声性能。Shaping 相关器消除了多峰模糊的特点,并在多径误差包络上要优于窄相关器以及HRC 算法,也很容易在原有基础上修改实现。该研究为未来的导航接收机中 Shaping相关器的应用打下了坚实的基础。-Abstract: Exis tin g algorithm s are worse when applied to binary
offset carrier ( BOC) signals than for the coarse/ acquisition ( C/ A)
code in GPS receivers. Th is paper pres ent s a new ref erence code f or
BOC s ignal t racking and gives the multipath error envelope compared
to the narrow correlat or method and high resolut ion correlat or. The
best reference code is determined by simulations and the noise
performance of the best reference code is analyzed. The mult-ipeak
fuzzyness is cancelled by a Shaping correlator. The performance of
the Shaping correlator ps multipath mitigaion is better than the
narrow correlator and the high resolution correlator.This correlator is easy to realizes the Shaping correlat or can be easily used in
future n avigat ion receivers.

Description: Direct sequence spread spectrum (DSSS) communication systems has been widely
used in these years for its advantage of wide spectrum, low working Signal-to-Noise
ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD.
They are increasingly replacing conventional communication forms and obtaining
extensively applications in modern military and commercial communication systems,
for example, CDMA communication system, GPS , measuring and control system,
satellite chain, identification of friend or foe and etc. Therefore, corresponding DSSS
electronic counter technique becomes a big problem to solve in electronic warfare
domain. DSSS electronic counter technique including blind detection, blind parameter
estimation and spreading sequences estimation. For the issue of DSSS electronic
counter technique of DSSS/QPSK signal damaged by strong additive white Gaussian
noise (AWGN), the main research content in this dissertation as follow.
