| 摘要: |
| 针对通信系统国产化的需求，采用国产射频收发芯片，从硬件与软件两个方面开发，设计了一套完整的软件无线电（Software Defined Radio，SDR）系统。以Zynq-7000芯片作为数字基带验证平台，利用Verilog和C语言进行开发，通过自主设计调制解调IP核，实现了全双工模式下无线数据收发功能。依据国产射频收发芯片系统架构，提出了一种改进型正交相移键控（Quadrature Phase Shift Keying，QPSK）结构，并通过自定义通信协议成功实现数据收发。该系统性能稳定可靠，能够在户外500 m以上的范围内有效通信，未出现误码，且功耗低于7.5 W。 |

| Abstract: |
| In response to the demand for localization of communication systems,a complete software defined radio(SDR) system is designed with domestically produced RF transceiver chips,and eveloped from both hardware and software aspects.Using the Zynq-7000 chip as a digital baseband verification platform,developed with Verilog and C language,and independently designed modulation and demodulation IP cores,wireless data transmission and reception functions in full duplex mode are realized.Based on the architecture of domestic RF transceiver chips, |
| Key words: software defined radio(SDR) domestic RF transceiver chip improved QPSK COSTAS loop |
