摘要
针对带内辐射功率的测量需求,提出了一种LTE终端带内辐射测量算法。该算法对基本带内辐射、IQ镜像和载波泄漏三种带内辐射功率分别进行计算,准确地测量了带内辐射功率。使用带内辐射测量算法分别对含有直流和消除直流的时域信号进行仿真,仿真结果证明该算法可用于测量带内辐射功率,结果准确可靠。
According to the demand of in-band ra- diation power measurement, this paper puts forward a kind of in-band radiation measurement algorithm for LTE terminal, which can calculate basic in-band radiation, IQ mirror and carrier leak accurately. In- band radiation measurement algorithm is used to re- spectively containing DC and eliminate the DC time domain signal simulation. The simulation results prove that the algorithm can be measured with radi- ant power, and the result is reliable.
