摘要

近些年來由於個人行動通訊之需求及發展，各種廣域或區域之無線及有線軍/民用通訊系統，隨者相關電子及通訊產業技術之創新及突破而蓬勃發展。然而，為遂行特定戰術性作為或目的，尤其針對戰術性通訊系統而言，及為降低敵方意圖偵測及截收整個通訊系統之私密資訊傳送性能，安全之通訊系統普遍需具備低信號偵測及截收率(LPD/I)性能，以降低敵方之信號偵測及截收效益。因此，研究如何評估通訊系統之低偵測/截收率(Low Probability of Detection/ Interception)性能便是本論文之重要研究課題。

Due to the requirements and developments of personal mobile communications for the past several decades, all kinds of global and local wireless/wire and military/civil communications systems are developing flourishingly in accordance with the novelties and breakthrough of all related electronic and communication techniques.
Nevertheless, in order to fulfill specific tactical operations or objectives, especially for the tactical communications systems, and to decrease the intentions of the adversaries to detect and intercept the transmissions of some specified private information, secure communications systems should have the low probability of detection and interception capability to lower the probability of being detected and intercepted by the adversaries. Therefore, it’s a very important research topic of this thesis to evaluate the performance of low probability of detection and interception (LPD/I).
