说明: 5. 在三条径的瑞利信道中,对于直接序列扩频:
(1) 请设计DS-CDMA一种具体的码分导引辅助的信道估计方法,接收机分别采用等均益合并、最大比合并。用Simulink进行仿真,测量BPSK的误码率性能,画出比特信噪比与信道估计均方误差的关系曲线,画出比特信噪比与误码率的关系曲线,请解释在误码率为0.01时,两种合并方式所表现的不同的物理意义。
(2) 设频率已经同步,请设计DS-CDMA一种具体的单停顿滑动相关时间同步方法,用Simulink进行仿真(自己编写代码S-Function方式),分析所设计方案的时间同步精度,画出比特信噪比与捕获概率的关系曲线。
(3) 设时间已经同步,请设计DS-CDMA一种具体的频率同步方法,用Simulink进行仿真(自己编写代码S-Function方式),画出比特信噪比与频率同步误差的关系曲线。
(5 In the three path Rayleigh channel, for direct sequence spread spectrum:
(1) Please design a specific DS-CDMA code division guide-assisted channel estimation, receiver, etc were used to benefit the merger, the maximum ratio combining. With the Simulink simulation, BPSK BER performance measure, draw-bit signal to noise ratio and channel estimation mean square error of the curve, draw the signal to noise ratio and bit error rate curve, please explain in bit error rate 0.01, the two methods are combined performance of the different physical meaning.
(2) frequency has been set up synchronization, a specific design of DS-CDMA single-stop sliding correlation method of time synchronization, simulation with Simulink (S-Function code their own way), analyze the design of time synchronization accuracy, draw bit signal to noise ratio and capture probability curve.
(3) set time has been synchronized, a specific design of DS-CDMA frequency synchronization method, simulation using Simulink ()

由于libsvm的matlab版本的工具箱libsvm-mat并没有给出寻参的函数模块,而无论利用libsvm工具箱进行分类还是回归,参数的选取是十分重要的,鉴于此libsvm-mat-2.89-3[FarutoUltimate3.0]在
libsvm-mat-2.89-3的基础上给出相应的辅助函数插件,方便用户来选取最佳的参数,现对该工具箱里主要的辅助函数插件的接口进行介绍。(As the matlab version of the toolbox libsvm libsvm-mat and did not give to find a function module parameters, regardless of classification using libsvm toolbox or regression, parameter selection is very important, in view of the libsvm-mat-2.89-3 [ FarutoUltimate3.0] in libsvm-mat-2.89-3 is given on the basis of the corresponding auxiliary function plugin user to select the best parameters, the toolbox is the main interface to plug the auxiliary functions are introduced.)
