由于多径和移动台运动等影响因素,使得移动信道对传输信号在时间、频率和角度上造成了色散,如时间色散、频率色散、角度色散等等,因此多径信道的特性对通信质量有着至关重要的影响,而多径信道的包络统计特性成为我们研究的焦点。根据不同无线环境,接收信号包络一般服从几种典型分布,如瑞利分布、莱斯分布和Nakagami-m分布。(Because multipath and mobile and other sports influence factor, makes mobile channel in transmission in time and frequency signal and Angle caused the dispersion, such as time dispersion, frequency dispersion, Angle dispersion, and so on, thus multipath channel of communication with the characteristics of quality is very important, while the effect of multipath channel (the statistical properties become the focus of our research. According to different wireless environment, receiving signals envelope general subject to several typical distribution, such as Rayleigh distribution, rice distribution and Nakagami-m distribution.

使用低通滤波器从含有噪声的信号中提取有用的正弦波
(见实验指导书 实验九 数字滤波器中的第一题)
目的:用数字滤波器从含有高频噪声的采样数据中提取正弦信号。
要求:①输入信号为一正弦波,并加入一个白噪声的干扰来模拟信号传输中的随机干扰信号(用以模拟含有噪声采样序列)。
(模拟含有噪声采样序列具体可用正弦波信号叠加高频噪声来实现,为了使滤波效果明显,本实验的高频噪声是用高频均匀分布白噪声(Uniform)通过Butterworth高通滤波器过滤生成的,高通滤波器的截止频率设为10倍输入信号频率。)
②在程序中设计一个低通巴特沃斯滤波器,以滤除信号中的噪声分量,提取输入的正弦波信号 。
③可调节信号滤波器的截止频率和阶数,可显示滤波前与滤波后的时域信号。
④给出滤波前与滤波后的频谱特性的显示。
