数字驱动由于其控制算法的灵活性可以有效地提高科氏质量流量计的工作性能。针对数字驱动的启振问题，本文基于模型分析和实验仿真，提出了正负阶跃交替激励启振方法。该方法通过跟踪检测传感器自激输出信号相位进行正负阶跃交替激励，使流量管的振动幅值持续、可靠地快速增大，进而结合非线性幅值控制算法和频率估计，可使流量管启振时间大幅度地缩短，克服了传统启振方法的局限性。-Digital drive control algorithm because of its flexibility can improve t

频域不同导频密度的信道估计在被研究，并且在高低时延信道其信道估计被固定了导频分配时域。频域信道估计是基于插补，多项式的广义线性模型（或最小二乘法）和维纳滤波（或线性最小均方误差法）的方法。时域的信道估计是用线性插补完成的。我们通过测量在基于克拉克散射模型的瑞利衰落信道上并带有QPSK调制的粗误码率，已经比较了所有这些方案的结果。-Different pilot density in frequency domain channel estimate to research, and its hi

本次实验主要是对一个正弦信号加入高斯白噪声，然后通过傅里叶变换对正弦信号进行谱估计。最后要用matlab进行仿真，得到正弦函数的时域和频域波形，关键找出信噪比和正弦信号频谱的均方误差之间的关系。-The experiment is a sinusoidal signal which is to white Gaussian noise, then by Fourier transform of the sinusoidal signal spectrum estimation. Finally,
