First, when the inter-user distance d is small, the SNR for D2D communication is high, and hence there are sufficient number of bits for high quality CSI exchange.

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。 (err)

波束形成算法是智能天线研究中最核心的内容。波束形成算法根据基于的对象不同可以分为基于方向估计的自适应算法，基于训练信号或者参考信号的方法和基于信号结构的波束形成方法；根据是否需要发射参考信号，分为非盲算法和盲算法。(The beamforming algorithm is the most important content in the research of smart antenna. Based on the beamforming algorithm according to the different objects can be divided into adaptive algorithm based on direction estimation method based on a training signal, or reference signal and signal beam forming method based on structure; according to whether to send the reference signal, divided into non blind algorithms and blind algorithms.)
