Gauss-Seidel

用matlab写的仿真H.263标准的程序，其中包括了基本的程序，还有测试程序(Matlab simulation written using H.263 standard procedure, including the basic procedures, as well as test procedures)

License Plate Recognition identifiable license plates of various mainland, including the blue card and card, yellow card and white card, black card to identify them from Hong Kong, Macao plate yellow card to identify the single-row yellow plates, large car number plates and motorcycle license white card can be identified, including a police vehicle, the armed police and military license plates.

图像的点运算：各种直方图的实现，直方图规定化，直方图均衡化。(Image point operation: all kinds of the realization of the histogram, histogram specification, histogram equalization.)

数字控制系统是一种以数字计算机为控制器去控制具有连续工作状态的被控对象的闭环控制系统。因此，数字控制系统包括工作于离散状态下的数字计算机和工作于连续状态下的被控对象两大部分。我的课题的数字部分（PID）仿真由相应的离散传函实现，运用数字PID对被控对象实行准确控制。通过调节比例（P）、积分（I）、微分（D），使对象的输出达到预期的效果。(Digital control system is a kind of digital computer for the controller to control a continuous state of the object and closed loop control system. Therefore, the digital control system, including work on the discrete state of the digital computer and work in a continuous state of the plant is two parts. My topic of digital section (PID) simulation by the realization of the corresponding discrete transfer function using the digital PID control of the plant is implemented accurately. By adjusting the ratio of (P), integral (I), differential (D), so that the output of the object to achieve the desired results.)

ofdm.m为主程序，可以运行，将得到迭加噪声之后的误码率曲线，并与理论QPSK加高斯白噪声误码率曲线比较，两者将重合(ofdm.m-based program, you can run, will be after the noise superposition error rate curve, and with the theoretical QPSK plus white Gaussian noise bit error rate curves, which will coincide)

说明：  去噪中的同步，从同学那拷来的例程，应该不错啊(Denoising synchronized copy came from the students that routines should be good ah)

Matlab实现FFT变换代码（包括单边谱及双边谱）(Matlab realization of FFT transform code (including unilateral and bilateral spectrum spectrum))

QPSK modulation system with recover loops(This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. The transmitter?s symbol period is T and set to a value of 100 ms. The symbol period at the receiver is Tr. The model will produce six windows: Two constellation plots and two eye diagrams (for the real part only), at the output of the matched fi lters and after the recovery loops a plot of the phase error (output of the NCO) and a plot of the fractional timing error (used in the interpolator). The frequency off set at the receiver is denoted by deltaf. The model simulates the transmission of 8000 QPSK symbols.)

说明：  合成矩阵,将各列最大元素提出来，记录原来位置，形成新矩阵(Synthesis of matrix, the largest element of the proposed column, record the original position to form a new matrix)
