  1. According to the target distance ( 5 ~ 50m ), a c - band transceiver for ranging was presented in this thesis. the focus of this work was on designing a c - band frequency - modulated continuous - wave ( fmcw ) frequency source, a receiver and microstrip antenna

    本文針對所探測目標的距離（ 5 ~ 50m ） ，研製了c波段測距收發前端，主要包括c波段調頻連續波（ fmcw ）頻率源，接收電路以及微帶天線。
  2. Based on the principle of light - pen mode non - track three dimensional coordinate measuring technology, the paper uses psd as the photoelectric receiver and point light modulated by frequency to measure coordinates

    本文通過對光筆式無導軌三坐標測量的研究、提出了以psd （ positionsensitivedetectors ，位置檢測傳感器）作為光電接收傳感器，用高頻調制光作為點光源，進行位置坐標測量的新思路，以提高整機的精度。
  3. In this paper, a smart - antenna base receiver compatible with the w - cdma standard is researched and designed. according to this standard, the up - link frequency band allocates from 1920mhz ~ 1980mhz, and the signal is modulated by qpsk schemes

    本文主要針對應用於w - cdma系統的智能天線接收機射頻前端進行研究和設計，此接收機應用於w - cdma系統上行鏈路（ 1920mhz 1980mhz ） ，採用qpsk調制技術。
