二次开发模块
一、条形码的批量生成，
款式：由存货(7)+颜色(2)+尺码(2)+供应码(2)+年份(4)+月份(2)+流水号(6)自由组合生成
面料：由存货(7)+颜色(2)+供应码(2)自由组合生成
（1）由于每件款式的条码是唯一的，其数据量相当大，在数据库存储方面若按以往的方式处理，估计数据库是无法承受。故需采用新的存储方式，在这存储方面就需花较多的时间方可解决。
（2）条码生成后需同时往用友数据库（表：InventoryBarCodeSet）插入数据，以供用友制单时提供对应关系。
-Secondary development of one module, the bulk barcode generation, styles: from inventory (7)+ Color (2)+ Size (2)+ Supply code (2)+ Year (4)+ Month (2) 2B ! serial number (6) to generate ensembles of fabrics: from inventory (7)+ color (2)+ supply code (2) free combination to generate (1) as a result of each style of bar code is the only, the amount of data quite large, if the database storage means in accordance with the previous treatment, it is estimated that the database is not unbearable. Therefore need to adopt a new way of storage in this storage area on the need to spend more time in order to resolve.

无线局域网仿真
WLAN仿真－发送机
wlan No Comments
设置完系统参数后，开始产生发送数据。
1. 产生随机的发送bit（tx_bits），这里不考虑信道编码。
2. QAM映射
3. 将数据映射到不同载波，形成OFDM符号
4. 产生pilot，并将pilot插入OFDM符号中
5. 加入dc和guard子载波
6. 进行ifft，将频域信号变到时域，并加入循环前缀
7. 对信号进行overlap window
8. 在时域产生short preamble
9. 在时域产生long preamble
10. 将preamble和数据符号组成packet
11. 升采样
得到信道传输的数据Tx_signal_up
具体程序见附件 wlan_transmitter.m-WLAN Simulation- wlan No Comments transmitter system parameters set finished, the beginning to have to send data. 1. Have sent random bit (tx_bits), here does not consider channel coding. 2. QAM mapping 3. The data is mapped to a different carrier to form OFDM symbols 4. Have a pilot, and pilot inserted OFDM symbols 5. Adding dc and guard subcarriers 6. To carry out ifft, will change the frequency domain signal to time domain, and add cyclic prefix 7. the signals overlap window8. In the time domain have a short preamble9. In the time domain have a long preamble10. the preamble and data symbols packet11. or sampling re
