Description: BCH 编解码的MATLAB 实现。BCH码是一类重要而有效的纠正多个随机错误的循环码，由于该码具有严格的代数结构，所以是到目前为止研究得最为详尽、应用最为广泛的一类码，已有多种译码算法。-BCH codec of MATLAB. BCH is a kind of important and effective redress the wrong number of random cyclic code, as the code strictly algebraic structure, it is so far the most detailed study in, the most widely used type of a code has a variety of decoding algorithm.

Description: 循环冗余校验CRC (Cyclic Redundancy Check)码是由分组线性码的分支而来，其主要应用是二元码字。编码简单且误判概率很低，在通信系统中得到了广泛的应用。循环冗余校验码是属于分组码中的一类重要的线性码，它不仅在理论上具有很好的代数结构，而且其编码和译码可以通过线性移位寄存器很容易地实现。
通过对CRC的分析和基于MATLAB工具的仿真，充分证明了CRC的检错能力很强，编码简单。
-Cyclic Redundancy Check CRC (Cyclic Redundancy Check) code is a linear code from the sub-branch from the main application is the binary code word. Coding is simple and very low probability of miscarriage of justice, in the communication system has been widely used. Cyclic redundancy check code is a block code in one important class of linear code, which not only has good in theory, algebraic structure, and its encoding and decoding of linear shift register can easily realize . CRC through analysis and simulation tool based on MATLAB, and fully proves that the CRC error detection ability of a strong, simple coding. Platform: |

Description: 一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，采用（7，4）循环码对信源做信道编码，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，再对信号进行信道解码，画出采用信道编码技术和不采用信道编码技术的误比特率图。-First, this program uses 16QAM modulation mode, for a string of two binary source is modulated, using (7,4) cyclic code of the source-channel coding to do with a raised cosine roll-off function for base-band modulation, and then transferred to a high frequency channel in the channel by adding Gaussian white noise, the use of matched filter demodulation, demodulation constellation plot, using the minimum Euclidean distance decoding decision, and then right channel signals, decoding, channel coding techniques used to draw and non- channel coding techniques using bit error rate plans.

Description: （7，4）系统循环码译码器
decode_out = cyclic_decoder(decode_in)
该系统循环码译码器的生成多项式是g(x) = x^3 + x + 1
输入参数decode_in是接收到的循环码字，是1×7的行向量；输出decode_out是解
码后的信息码字，是1×4的行向量。
函数运行时，同时画出接收循环码字和译出码字的波形图。
- (7,4) system cycle Decoder decode_out = cyclic_decoder (decode_in) cyclic code decoder of the system generating polynomial is g (x) = x ^ 3+ x+ 1 input parameters decode_in is the received codeword cycle, the row is 1 × 7 vector output decode_out solution code is the information after the code word is 1 × 4 row vector. Function to run at the same time code word and draw a circle to receive the word of the translated code waveform. Platform: |
