about Accounting Version 3 This guide explains how to use Eshan Accounting accounting and enterprise resource planning (ERP) software to run your business. It focuses on things an entrepreneur or business owner needs to know and do to run a real business rather than on describing each function of the software. In fact, you won’t find every little detail about Eshan Accounting here, especially if an item seems easy enough to figure out by reading the screen. Instead, you’ll see how each feature works together to run real businesses. Some elements of an accounting system may be unfamiliar to you, especially if you don’t have an accounting background or are using an ERP for the first time. I try to explain them as I cover each one below.

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

用MFC对话框做的ofdm系统的仿真程序，很形象，比较适合ofdm的初学者(To do with MFC dialog ofdm system simulation program, it is the image more suitable for beginners ofdm)

设采样频率为1Hz，对于淹没在复高斯白噪声中的信噪比为 的两个复LFM信号，采用子带带宽为0.1Hz的升余弦滤波器，共9个子带滤波器构成的滤波器组，时间窗为窗长为256的矩形窗，进行仿真(based sampling frequency of 1Hz. For drowned in the complex Gaussian white noise to the signal-to-noise ratio of 2 Minute LFM, using sub-band bandwidth of 0.1 Hz or cosine filter, a total of nine sub-band filter a filter group, time window to window to 256 long rectangular window simulation)

实现了对语音信号的FFT处理，用matlab(Realization of the speech signal FFT processing, using matlab)

IT IS TO TRAIN SOM NETWORK ON IMAGE .......
