代码说明：

说明：  一架飞机在海上失事，搜救人员打捞出了该机的黑匣子，技术人员从其中的内存里恢复了一段声音plane.wav，经推断该声音是失事之前最后时刻的数据，设备供应商证实该声音是通过频分复用生成后准备发送出去的，复用的其中一路信号可能含有驾驶员最后发出的指令，现在要求对该声音进行分析，并恢复可能存在的指令，同时能够利用平台实时播放提取的信号。 内含matlab和CCS两份代码(A plane crashed at sea, search and rescue personnel salvaged the black box of the plane, the technician recovered a piece of sound plane.wav from its memory, and it was inferred that the sound was data at the last moment before the crash, and the equipment supplier confirmed the sound It is prepared to be sent out after being generated by frequency division multiplexing. One of the multiplexed signals may contain the last command issued by the driver. Now it is required to analyze the sound and restore the possible instructions. At the same time, the extracted signals can be played in real time using the platform.)
