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

哈夫曼码的编码译码系统 问题描述 利用哈夫曼编码进行信息通讯可以大大提高信道利用率，缩短信息传输时间，降低传输成本。但是，这要求在发送端通过一个编码系统将待传输的数据预先编码：在接受端通过一个译码系统对传来的数据进行译码（复原）。对于双向传输信息的通道，每端都需要一个完整的编码译码系统。试为这样的信息收发站编写一个哈夫曼码的编码译码系统。-Huffman coding code decoding system describes the use of Huffman coding information can be greatly improved communication channel utilization, reduced transmission time, and lower transmission costs. However, this requires the transmitter through a coding system will be pre-transmission of data encoding : the receiving end through a decoding system to conduct data from the decoder (recovery). For the two-way transmission of information access, each side needs a complete Coding System. Examination of this information hubs to prepare a code of Huffman coding decoding system.

Grid 控件应该分成自由式
报表和数据相关表格两种，其内部实现机理不尽相同，你说的要求恰恰要把这两种风格的
报表融合起来：Exel 是典型的自由式报表，复制、拖拉、合并单元格等，它的每个单元格
都是相对独立的，数据相关表格就很不一样了，最典型的就是它有数据列的概念。
-Grid Control Report should be divided into freestyle and data related to table two, the internal mechanism of implementation is different, you said it to the requirements of these two styles together Report: Exel is a typical freestyle Report, copy, drag and drop, merger cells and so on, each of its cells are relatively independent, data related to very different on the table, the most typical is that it has the concept of data columns.
