在這篇文章中,首先我們在頻率非選擇性衰減通道環境中,利用時空漢克編碼(Hankel space-time block code)結構的特性,在接收端以旋轉特徵分解法來進行盲目的解碼,此編碼具有傳輸率為一(full transmission rate)的特性。模擬結果顯示在不同天線個數下對系統效能的表現。 此外我們提出時空湯普利斯區隔編碼(separated Toeplitz space-time block code) ,在頻率選擇性衰減通道環境下以旋轉特徵分解法所求得的半盲目等化器來直接估計信號,此編碼具有全散度(full diversity)的特性。模擬結果顯示在頻率選擇性衰減通道環境下,比較於其他的方法具有較明顯的系統效能改善。
In this paper, at first we decode the Hankel space-time block code over frequency non-selective fading channel by using transformed-eigen decomposition (TED) method. It shows this code achieves the full transmission rate diversity without full diversity. Simulation results are presented to demonstrate the performance of the proposed method. Another, we proposed the separated Toeplitz block code over frequency selective fading channel by TED method. It shows this code achieves the full diversity with less efficient transmission rate. Simulations show that the performance of the proposed method compared with the well known the methods performs well.
