用 matlab实现均值滤波去高斯白噪声 用 matlab实现中值滤波去噪声 用理想低通滤波器在频率域实现低通滤波(Mean filter with matlab to implement Gaussian white noise with median filter matlab to achieve the ideal low-pass filter with the noise in the frequency domain low pass filter)

说明：  基于置信传播算法和Viterbi检测的ISI信道估计，比较两种算法的性能(ISI channel is estimated based on the belief propagation algorithm and Viterbi detection, compare the performance of the algorithm)

本程序主要通过仿真动态显示均匀平面电磁波中，磁场 Hz 的波阵面在自由空间（理想介质）中的传播。(The program primarily through dynamic simulation shows uniform plane wave, the magnetic field Hz wavefront in free space (ideal medium) in the transmission.)

In this paper we propose a system using CCMA codes concatenated with block RLWECC which can support multimedia services over UMTS sharing same radio resource without usage of any extra bandwidth.

去斜率（strech）参考信号与回波信号混频后得到中频输出信号S(t)=Aexp(j*2*pi*f0*t+phase) 其中f0与回波延时的关系为： f0=k*delay_t K为线性调频斜率，delay_t为回波延时 将s(t)采样，FFT变换即可得到目标距离与频谱的关系。 Strech 信号测距 输入混频后的中频信号（图一），经采样及FFT变换得到频谱（图二） 再根据频谱与距离的关系式R=Tcf/2B显示出距离(图三) (Go slope (strech) obtained after the reference signal and the echo signal mixer IF output signal S (t) = Aexp (j* 2* pi* f0* t+phase) f0 and echo delay relationship: f0 = k* delay_t K chirp slope, delay_t the echo delay sampling s (t), the FFT transform to the target distance spectrum of relations. Strech signal ranging input mixer IF signal (Figure 1), sampling and FFT transform spectrum (Figure 2) according the the spectrum distance relationship R = Tcf/2B shows the distance (Figure 3))
