【摘要】 设计与搭建了工作在220GHz的短程无线模拟通信系统与数字通信系统,通信距离为0.6m。在模拟通信系统中,实现了音频信号(WAV格式)的实时传输与接收,达到了理想的播放效果。在数字通信系统中,实现了对文件(图片、音频、视频等)的加密、格雷编码、格雷解码与解密,由于受制于采集卡采样速率的硬件限制,实现的最大数据传输速率为1Mbit/s。更多还原

【Abstract】 In this paper,220GHz short-range analog wireless communication system and digital wireless communication system have been designed and built respectively with the communication distance of 0.6m.In the analog communication system,the real-time transmission and receive of the audio signal(WAV format)has been realized,and the sound effect of this system is as good as expected.In the digital communication system,the encryption,gray encoding,gray decoding and decryption of files,such as picture,audio and video,has been realized.Due to the hardware limitation of the data acquisition,the sampling rate of which is 1Mbit/s,the maximum data transmission rate achieved is also 1Mbit/s.更多还原
