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

一般使用PC Based Controller 都是当作现场设备的一种,也就是要接受
主系统的命令,做一些操作控制。以Modbus 来看属于Slave 的角色,随
时等待接收Modbus Master 的Query Message,然后依据内容做控制,最后
将控制结果以Response Message 回传。本章将以ICP 7524 及ICP 7188E5 等
两种设备分别设计Modbus RTU、ASCII 及Modbus/TCP 的Slave 应用程序,
读者可以将此两种程序的架构再延伸设计至各种实际应用程序。-Generally used as a PC Based Controller is a field device, which is the main system to accept orders, make a number of operational control. Modbus is a look at the role of Slave, Modbus Master at any time waiting to receive the Query Message, and then to do based on the contents of control, the final results will be controlled in order to return the Response Message. This chapter will be ICP 7524 and ICP 7188E5 equipment design, such as two Modbus RTU, ASCII and Modbus/TCP the Slave application, readers can use this framework for the two procedures designed to further extend the range of practical applications.
