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 ()

利用该代码可以轻松实现模糊聚类分析 具体运用只需要直接在主程序上赋给分析的数据矩阵 便可以得到聚类图以及相关分析结果 也许不是很完美 实际应用可以小作调整(The matlab code is useful in fuzzy mathematics.)
