Description: WLAN仿真－系统参数配置
系统参数主要分为2类：
一类是可以配置的，可以根据使用者的需求改变的参数
1）你打算让这个仿真跑多少个OFDM符号？
2）你打算采用什么样的调制方式？
3）你打算让你的系统跑在什么样的环境下，AWGN？Rayleigh fading?
4）你的接收端采用什么样的配置，比如，是否采用理想均衡，线性插值均衡，理想同步，频偏纠正等等？
5）你的信道采样频率是多少？你的载波频率是多少？
一类是固定不变的，发送端按照协议规定设置的一些参数
1）子载波个数，包括数据子载波，导频子载波。
2）保护间隔，pilot和preamble的数值。
举例：比如将这些参数汇总在一个m文件，global_parameter.m-err

Description: 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 received data transmission channel Tx_signal_up specific procedures see Annex wlan_transmitter.m

Description: 802.11a wlan物理层仿真，里面有三个物理模型，均用MATLAB编写-802.11a WLAN PHY
There are*three* versions of the 802.11a physical layer model:
R13/IEEE80211a.mdl:
Requires R13 (MATLAB ) and Stateflow (for adaptive modulation control)
R13/IEEE80211a_NoSF.mdl:
Requires R13 (MATLAB), but does not require Stateflow.
R13SP1/IEEE80211a.mdl
Requires R13SP1 (MATLAB), but does not require Stateflow.
This latest version also includes some bug fixes.
All Simulink models require the Communications Blockset.

Description:
The simulator GUI is started with command ui_start in Matlab command window.
WLAN simulation starts by clicking the Start Simulation button in the GUI window.
WLAN simulation can be terminated, before set number of packets have been reached by pressing control-C .
##### Version updates and bug fixes
January 24th 2002: A bug in file rx_qpsk_demod.m fixed
July 31th 2002: A bug in file rx_gen_chan_amps.m fixed. This bug affected performance in fading channels.
April 15th 2003: Changed the code not to require functions from the Matlab Communications toolbox.
