摘　　要：为了解决雷达及电子对抗系统组网协同工作的问题,设计一种基于QPSK调制解调的高速无线数传链路,并对其进行仿真及FPGA硬件实现。利用QPSK调制信号功率集中、带外泄漏少、载波抑制的优点,将其设计成为组网系统的底层通信链路。该无线数传链路中频频率150MHz,传输信息速率为10Mbps,为了适应各子平台(站)相对运动的通信环境,在外加10kHz载波频偏的条件下进行蒙特卡洛仿真,在5dB信噪比条件下误码率达到10e-5的量级,接近理论值。For the problem of cooperative combat networking of radar and ECM system, a new wireless data communication based on QPSK modulation method is introduced. And simulation and hardware implementation with FPGA of this method is introduced. The QPSK modulation is designed to link layer of co operative combat networking because of the power concentration, carrier suppression and without out band leakage. The medium frequency of wireless data link is 150MHz, and transmission data rate is 10Mbps. To adapt to the relative movement communication environment, the Monte Carlo method is used in the condition of 10kHz Doppler frequency shift and SNR is 5dB. In this condition, the Bet is up to 10e-5 and it is closed to theoretical value.
