ZHAO_OFDM
这个程序除了接收机同步、信道编码没有加入外，基本上反映了一个OFDM系统的特性： 1. qpsk/16qam/64qam映射、解映射 2. OFDM调制解调（循环前缀，FFT等） 3. 非整数采样时刻多径时延的多径信道 4. Rayleigh或者Rician多径信道 5. 信道的连续时变（非block fading） 6. 线性插值信道估计 7. FFT变换域插值信道估计(In addition to this program receiver synchronization, channel coding have not joined, the basically reflect the characteristics of an OFDM system: 1. Qpsk/16qam/64qam mapping, mapping solution 2. OFDM modulation and demodulation (cyclic prefix, FFT, etc.) 3. Non- integer sampling instant multi-path delay of multi-path channel 4. Rayleigh or Rician multipath channel 5. a continuous time-varying channel (non-block fading) 6. linear interpolation channel estimation 7. FFT transform domain interpolation channel estimation)

模仿超级终端风格的RS232串口调试工具这是一个模仿Windows系统带的超级终端风格的RS232串口调试工具。非常容易读取和写入端口，发送支持ASCII字符模式，可以打开二进制文件以16进制格式显示发送。支持工作内容保存，下次加载。里面的那个动画窗体加载出现蛮有意思，大家可以学习下。尤其对调试AT指令之类的比较方便。(RS232 serial debug tool imitating super terminal style This is a SuperTerminal style RS232 serial debugging tool that mimics the Windows system. It is easy to read and write ports, send ASCII character mode and open binary files to display in 16 binary format. Support work content to save, next load. Loading the animated form inside is quite interesting. You can learn from it. In particular, it is more convenient to debug AT instructions.)
