1、FIR数字滤波器的设计（1）在主函数中调用dsnFIR函数，滤波器参数设为21阶、带阻、矩形窗、采样率1000Hz、上下截止频率分别为100Hz,400Hz；（2）利用drawFIR函数分别画出所设计的FIR滤波器的幅频特性图和相频特性图。2、FIR数字滤波实现（1）编写一个输入信号子程序func()，输入信号为一连续函数，表达式为；（2）对输入信号进行采样，即       ，这里取采样率，得到离散序列x(n)；（3）取x(n)中前40个点的值，将其转为复数存入复数数组x[64]中，并对x[64]做64点的FFT，得到的X(k)存回x[64]中；（4）已知在主函数中调用dsnFIR函数后得到的输出结果b[21]即为FIR滤波器单位冲激响应h(n)的值，将其转为复数存入复数数组h[64]中，并对h[64]做64点的FFT，得到的H(k)存回h[64]中；（5）已知用FIR滤波器对输入信号进行滤波就是将输入信号x(n)与滤波器单位冲激响应h(n)做卷积运算，故我转到频域采用FFT方法实现对输入信号x(n)的滤波，即将X(k)与H(k)相乘，得到滤波后信号的FFT变换Y(k)，然后只需对Y(k)做IFFT变换即可得到滤波后信号y(n)。

QAM调制的基本原理 QAM调制实际上是幅度调制和相位调制的组合。相位 + 幅度状态定义了一个数字或数 字的组合。QAM的优点是具有更大的符号率，从而可获得更高的系统效率。通常由符号率 确定占用带宽。因此每个符号的比特（基本信息单位）越多，效率就越高。-QAM modulation of the basic principles are in fact QAM modulation amplitude modulation and phase modulation of the portfolio. Phase+ margin status defines a combination of numbers or figures. The advantage of QAM symbols are greater rate, thus the system efficiency will be higher. Symbol rate is usually determined by the occupied bandwidth. Thus each bit symbols (basic units of information) the more the higher the efficiency.
