here is the matlab source code for parallel port communication

该程序完成一个16电平PAM数字通信系统的仿真，并测量了它的误码率。首先产生信息符号序列，该序列被当做4个信息比特一组，将16组符号映射到16个信息幅度。检测器计算距离，输出与真正传输的信息符号序列作比较，然后将差错计数。( This procedure completes a 16 level PAM digital communication system s simulation, and has surveyed its error rate. First has the message digit sequence, this sequence is treated as a 4 information bit group, maps 16 class symbols to 16 information scopes. The detector estimated range, the output and the true transmission s message digit sequence does compares, then counts the mistake. )

说明：  一本很透彻地讲解如何利用MATLAB来进行生物信号处理的外文电子书。(A very thorough to explain how to use MATLAB for biological signal processing foreign language books.)

说明：  这是用三角分解法求解线性方程组的一种方法(This is a triangular decomposition method for solving linear equations method)

LDPC的解码程序，可以更理解LDBC的解码过程(LDPC decoding process can be more to understand LDBC decoding process)

实现FASTICA算法，可以将高维数据映射到二维坐标上！(Achieve FASTICA algorithm can be high-dimensional data is mapped to the two-dimensional coordinate!)

CRC校验码的Matlab源程序,希望对大家有帮助(CRC Checksum Matlab source code, I hope all of you help)

maple写的基本kalman算法，可以做入门参考理解(maple write basic kalman algorithm, can be understood to do entry-reference)

MA11AB与VC++混合编程，开发了水轮机综合特性曲线数据处理系统。该系 统利用VC++友好的界面编程对水轮机综合特性曲线已知区域数据进行提取，使用MATLAB 搜索引擎调用RBF人工神经网络库对提取数据进行拟合并结合边界约束条件对未知区域内的 数据进行预测(MA11AB with VC++ mixed programming, developed the turbine characteristic curve of integrated data processing system. The system uses VC++-friendly programming interface integrated characteristic curve of the turbine region are known to extract data, using MATLAB search engine called RBF artificial neural network to extract data from the Treasury to be bound by the conditions of the merger combined with the border region of the unknown data Forecast)

采用16QAM调制方式对一串二进制信息进行基带调制，并分析其功率谱，在AWGN信道上进行传输，并解调，最后对其误比特（BER）性能加以分析。(Using 16QAM modulation methods on a string of binary information in the baseband modulation, and analyze the power spectrum, in the AWGN channel for transmission, and demodulation, the last of its bit error (BER) performance analysis.)
