摘要： 为了满足未来空间高速通信的迫切需求，进行了W波段(75~110 GHz)无线高速通信的研究。通信系统中采用光子上变频技术产生传输速率为20 Gbit/s的W波段QPSK信号，解决了电子器件带宽受限的瓶颈问题。在接收机端采用模拟下变频和先进数字信号处理技术，实现了无线传输360 m距离后信号的离线解调。最终系统的误码率小于硬判决前向纠错(FEC)门限3.8×10?3。

Abstract: In order to meet the demand of future high-speed space communication, a high-speed wireless communication system at W band (75~110 GHz) was investigated. For solving the bottlenecks of bandwidth-constrained electrical components, the communication system adopted photonic up-conversion technology to generate 20 Gbit/s W-band quadrature phase shift keying (QPSK) signal. At the receiver, analog down-conversion and advanced digital signal processing technology were adopted to realize the off-line signal demodulation after 360 m wireless transmission. The bit error rate (BER) of the system is less than the hard-decision forward error correction (HD-FEC) threshold of 3.8×10?3.
