针对传统的单边带电台采用模拟实现技术存在的缺点,采用软件无线电设计思想,以数字信号处理技术为核心,设计了一种短波单边带数字化无线收发机。该单边带收发机采用宽带低通射频采样结构,利用数字上下变频技术实现从基带到射频之间的转换,以及正交调制解调方式。提出了基于现场可编程门阵列(FPGA)硬件平台的收发机设计思路与实现方法,仿真与实验结果表明,所设计的单边带收发机各功能部件均符合设计要求,总体性能也达到预期的效果。
Aiming at the shortcomings of traditional single sideband radio using analog technology, this paper designs a shortwave single sideband digital wireless transceiver based on the idea of software radio design and digital signal processing technology. The single-sideband transceiver uses a wideband low-pass RF sampling structure, using digital up-conversion technology to achieve conversion from baseband to RF, and quadrature modulation and demodulation. A design idea and implementation method of transceiver based on field programmable gate array (FPGA) hardware platform are proposed. The simulation and experimental results show that the designed single-sideband transceivers meet the design requirements and the overall performance reaches the expected effect.
