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。

基于频谱细化的线性调频信号的参数估计。首先对中频信号延时相乘然后对产生的序列做FFT,初步算出LFM信号的调频斜率,然后用CHIRP-Z变换精确估计。(Estimated based on the parameters of the linear FM signal spectrum refinement. First of delay multiplied by the IF signal and then do the FFT on the resulting sequence, initially calculated the slope of the LFM signal FM accurate estimate, and then use the CHIRP-Z transform.)
