本文中探討長距離跨海微波通信之鏈路分析及量測需求以實現高容量(STM-1)、高速率(171Mbps)之傳輸設計。海平面反射係數分析、High-Gain Pattern產生及K值變化對接收信號強度之影響分析，使應用於微波通徑之高增益指向性天線的位置與天線間距達到最佳位置，俾使接收機獲得非相干之接收信號強度，以對抗反射波之衰落效應。
天線及導波管系統品質之良窳影響長距離跨海微波通信性能甚鉅。本文將提出如何在維持微波鏈路為 規範下，天線及導波管系統Return Loss之量測需求，以避免因天線及導波管系統之非連續性效應或呈現非線性響應而導致接收端之嚴重ISI或同(鄰)頻干擾。另有關干擾所造成之接收靈敏度衰落分析亦將本文中討論之。
由測量數據可知，提升發射機之輸出功率並不能使多重路徑的衰落效應改善，而僅使用Slope等化均衡器或抗Notch 濾波器等在頻域上的作為亦無法有效對抗多重路徑衰落，惟作用於時域上的適應性等化均衡器(ATDE)可提供明顯有效的改善。本文將討論ATDE在微波通信上之操作模式及其在不同等級之效率評估，以作為計算對抗多重路衰落效應之能力以及微波鏈路可靠度分析之預估。

In this thesis, one long-haul over the sea surface microwave radio link is analyzed and the measurement requirement is proposed, such that a high capacity (STM-1) and high speed (171Mbps) transmission design can be realized. The analysis of sea reflection coefficient, the obtained high-gain pattern and the analysis between the K-value change and the receiver signal level fluctuation are all the factors to decide the optimal antenna height and spacing. Therefore, the uncorrelated signals can be obtained between the main and diversity antenna and the simultaneous cancellations of signals can be avoided.
The quality of installation for Antenna/Waveguide system plays a very important role since it will generate echoes to result in the ISI appearing on receiver input if there is any impendence mismatch occurred in the conjunction. The measurement requirement derived from radio echo requirement for satisfying specification is proposed. In addition, the interference to cause receive sensitivity degradation is also discussed in this thesis.
The measurement records show that the increasing output power will not alleviate the multipath fading effect suffered by receiver. The use of diversity and time domain adaptive equalization (TDE) have been found to greatly mitigate the effects of dispersive fading, allowing performance objectives to be met for digital radio. The prediction models for multipath channels show that the performance of equalization technology has a great impact on the result of outage probability.
