摘要
本实验采用74 GHz本振源与一对矩形喇叭天线实现了非归零开关键控(NRZ-OOK)信号在室内环境下的传输。在实验中还研究了不同传输距离和速率对系统性能的影响。结果表明误码率性能随着距离和速率的增加而下降,使用前向纠错编码(FEC)的5 Gbit/s和6 Gbit/s信号可以在3.6 m内实现无误码传输,而7 Gbit/s信号只能在2.4 m内实现无误码传输。
The Non-Return-to-Zero On-Off Keying (NRZ-OOK) signal transmission is demonstrated indoors with a 74GHz local oscillator and a pair of rectangular horn antenna. The BER performance of the system is researched with various transmission distances and bit rates. The results show that the performance decreases with the increasing of distance and bit rate. Error free transmission can be realized within 3.6m for 5Gbit/s and 6Gbit/s signals with Forward Error Code(FEC), while just 2.4m transmission can be realized for 7Gbit/s signal.
