Matlab Filter Implementation
In this section, we will implement (in matlab) the simplest lowpass filter
$displaystyle y(n) = x(n) + x(n-1), n=1,2,ldots,N $
(from Eq.$ ,$(1.1)). For the simplest lowpass filter, we had two program listings:
Fig.1.3 listed simplp for filtering one block of data, and
Fig.1.4 listed a main program for testing simplp.
In matlab, there is a built-in function called filter3.3 which will implement simplp as a special case. The syntax is
y = filter (B, A, x)
where
x is the input signal (a vector of any length),
y is the output signal (returned equal in length to x),
A is a vector of filter feedback coefficients, and
B is a vector of filter feedforward coefficients.
The filter function performs the following iteration over the elements of x to implement any causal, finite-order, linear, time-invariant digital filter:3.4

根据伪随机序列理论，由混合同余法产生均匀分布的随机数，进而根据中心极限定理来产生高斯噪声。
分析所产生的均匀分布和高斯分布随机信号的均值、方差、自相关等数字特征，估计其概率密度函数并进行分析，估计其功率谱密度并进行分析。说明该高斯噪声是否符合白噪声特性。
对该高斯噪声进行FIR低通滤波，估计输出低通型限带白噪声的功率谱、相关时间等，并结合白噪声通过线性系统相关理论来进行分析。
(According to the theory of pseudo-random sequence, a uniformly distributed random numbers by mixed congruential method to generate Gaussian noise, and then according to the central limit theorem. Produce a uniform distribution of the analysis and the mean of the Gaussian distribution random signals, variance, since the digital characteristics of the correlation, the probability density function is estimated and analyzed, it is estimated that its power spectral density, and analyzed. The Gaussian noise is in line with the characteristics of white noise. FIR low pass filter of the Gaussian noise, the estimated output of low-pass type band-limited white noise power spectrum, time, etc., combined with the white noise to be analyzed by linear system theory.)

提高数据传输效率，降低误码率是信道编码的任务。信道编码的本质是增加通信的可靠性。但信道编码会使有用的信息数据传输减少，信道编码的过程是在源数据码流中加插一些码元，从而达到在接收端进行判错和纠错的目的(Improve the efficiency of data transmission, reduce the bit error rate is the channel coding task. The essence of channel coding is to increase the reliability of communication. But the channel coding can make data transmission of useful information is reduced, the channel coding process is to add some symbols in the source data stream, so as to achieve the purpose of erroneous judgment and correction at the receiver)
