[Other] perfect_OFDM

Description: 还在为“基于MATLAB的OFDM系统仿真”的朋友，可以看看我总结的资料！ 该代码通过综合了本站中的两个源代码，在MATLAB 7.0下完成OFDM系统的完美仿真：音频数据采集->S/P转换->16QAM映射->IFFT处理->添加CP->P/S->理想/多径信道传送->……（FFT等）->传输结果比较（前后频谱图、可以直接通过听前后的音频文件来辨别系统的好坏-理想信道时音质前后相同）。在此还要感谢那两位站员提供相关的代码，也希望能对其他人有帮助。更希望本站能吸引更多的编程爱好者再创佳绩。-KEYWORD:OFDM MATLAB 7.0 CP IFFT FFT P/S S/P Also for the " Based on MATLAB simulation of the OFDM system," a friend, you can see my summary of the information! The code through a combination of the two site source code, MATLAB 7.0 at complete perfection OFDM system simulation: Audio Data Acquisition-> S/P conversion-> 16QAM mapping-> IFFT processing-> Add CP-> P/S-> ideal/multi-path channel transmission-> ... ... (FFT, etc.)-> transmission results (before and after the frequency spectrum can be directly before and after listening to audio files to identify the system good or bad- when the ideal channel before and after the same sound quality). This would also like to thank at the two stations to provide the relevant code, also hope to have helped others. I also hope to attract more site programming enthusiasts new heights.
