【摘要】 为了验证极化域频谱共享功能,基于USRP和GNU Radio这一SDR(Software Defined Radio)环境,利用虚拟极化理论,在发现并解决了USRP引入的相位误差的基础上,实现了一个能够进行极化域频谱共享的基础平台;利用此平台对极化域频谱共享方案进行了实际场景测试,测试结果表明了极化域频谱共享方案的可行性。更多还原

【Abstract】 A USRP(Universal Software Radio Peripheral) and GNU Radio based testbed is implemented for testing the spectrum sharing utilized polarization state.For implementing this testbed,virtual polarization theory is used and phase difference brought by VCO/PLL(Phase-Lock Loop) chains in different daughtboards is corrected with SDR(Software Defined Radio).The test results of spectrum sharing utilized polarization state with this testbed show it is feasible.更多还原
