高頻（High Frequency，HF）通訊系統因可藉由電離層（Ionosphere）反射實現超視距遠距傳輸，至今仍廣泛應用於軍事通訊場域。美軍與北約共同制定第三代自動鏈路建立（3rd Generation Automatic Link Establishment，3G ALE）標準規範，其中定義了多種Burst Waveform，以滿足不同通訊需求。 本論文依據上述標準規範，針對 3G ALE 系統中之高速傳輸波形與低速傳輸波形進行完整的設計，並以 C 語言實現其資料處理流程，於加性白色高斯雜訊（Additive White Gaussian Noise，AWGN）通道下模擬驗證其位元錯誤率（Bit Error Rate，BER）效能。 模擬結果顯示，兩種波形之 BER 效能均隨自動重傳請求（Automatic Repeat reQuest，ARQ）迭代次數增加而顯著改善。低速傳輸波形在惡劣通道條件下具備更強的抗雜訊能力，適用於信雜比較低之高頻通訊場合；高速傳輸波形在通道條件較佳時展現更高的頻譜效率，並透過區塊交織器提供對叢錯誤之防護能力。;High Frequency (HF) communication systems exploit ionospheric reflection to achieve beyond-line-of-sight transmission and continue to serve as an indispensable means of military communication. The United States military and NATO have jointly established the 3rd Generation Automatic Link Establishment (3G ALE) standard， which specifies multiple burst waveforms to satisfy diverse communication requirements. This thesis presents the complete waveform design for both the high-rate and low-rate transmission waveforms of the 3G ALE system， implemented in C and verified through Bit Error Rate (BER) simulation under an Additive White Gaussian Noise (AWGN) channel. Simulation results demonstrate that both waveforms achieve significant BER improvement as the number of Automatic Repeat reQuest (ARQ) iterations increases. The Low-rate waveform provides stronger noise immunity under adverse channel conditions， making it suitable for high-frequency communication links with poor channel quality. The high-rate waveform exhibits higher spectral efficiency under favorable channel conditions and offers additional protection against burst errors through its block interleaver. These findings provide a theoretical foundation for future work on fading channel simulation and hardware realization.
