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
