Construction of a fixed
介绍了一种构建在定点DSP上的高速瑞利衰落信道仿真模型。通过应用确知性瑞利过程的理论,使得仅需要较少的低频正弦波分量以及简单的运算即可实现较高精度的信道建模;进而可采用查表法并结合TMS320C6202定点数字信号处理器的高并行性和处理能力构造高速的仿真模型-Construction of a fixed-point DSP in the high-speed Rayleigh fading channel simulation model. Through the application process unascertained Rayleigh theory, only need to make small low-frequency sine wave components and the simple operation can achieve higher accuracy Channel modeling; then use look-up table method and combination TMS320C6202 fixed-point digital signal processor parallel and can handle Construction of the high-speed simulation model

简易FIR滤波器
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)。
