本文报告了一种使用无线线性调频扩频波形进行室内定位的射频电路设计。首先解决现有硬件系统的技术问题，然后指出测距电路的主导因素。结果表明，通过阻止时钟噪声的影响可以显着提高现有系统的性能。开发并测试了一套实验硬件电路。
This paper reports an RF circuit design for indoor localization using wireless chirp spread spectrum waveform. First we address the technical problems of existing hardware systems and then point out dominant factors of the ranging circuit. It will be shown that the performance of the existing system can be significantly enhanced by blocking the effects of clock noise. A set of experimental hardware circuits is developed and tested.
