Implementation of UHF Radio Test Set Based on Digitalization

现场无线通信电台测试系统要求小型化、多功能、数字化、软件化。本文将数字信号处理与电路实现结合,基于DSP/FPGA技术、优化设计的收发通道,简化了电路实现、提高测试性能、减小体积、降低成本。本设备已获得了运用,下一步将推广到宽带扩频与数字调制系统的测试。

The field test-set of radio communication system should be small size , multifunction, digitalization, software realization. This paper composes digital signal processing and circuit optimum, designs a practical test-set based on DSP/FPGA and optimum implementation of transceiver, make the test-set circuit simple, size and cost minimized, and performance improved. The test-set have gotten application in a testing system of air force. The next goal is to improve the set to meet the testing of wideband, spread spectrum and digital modulation.
