各种时频分析工具包part1,非常有用的!忘了是哪位大哥发的,现转发到这,希望对大家有所帮助!-A variety of time-frequency analysis tool kit part1, very useful! Forgot who made Big Brother, it is forwarded to it, and they hope to be helpful to everyone!

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

进制转换的一个很好的函数。可在16进制内自由转换，也可创新地使用5、6、7等进制格式。经过简单改造后可使用最大36进制的形式。是编程人员的一个好东东。-base for the conversion of a good function. 16 in the 229 free conversion, but also innovative use of 5, 6, 7, etc.-band format. After simple transformation can be used after the 36 largest 229 forms. Programming staff is a good Eastern.

安捷仑的数字调制信号发生器E4438用于很多通信系统的开发过程中。本代码可以用于通过网络接口或GPIB接口向E4438下载被调制数据-Ansett in 2000 digital modulation signal generator E4438 used in many communications systems development process. The code can be used by the network interface or E4438 GPIB interface to download data to be modulated
