  • Warrier和 Madhow在2002年提出對於非同調通訊使用振幅/相位星座圖的廣義可能性機率測試(GLRT)法和趨近最佳化的低複雜度檢測演算法。他們也提出ㄧ種用於振幅/相位星座圖的能量限制方法。根據由GLRT檢測法所得到的最小非同調距離,吾人提出新的用於兩層振幅星座圖的能量控制方法來得到比原始的能量控制方式還要好的錯誤效能。吾人亦提出用於三層振幅的非同調編碼調變的方法更進ㄧ歩改善其錯誤效能


    In 2002, Warrier and Madhow proposed generalized likelihood ratio test (GLRT) detection and near-optimal low complexity detection algorithm for noncoherent communication using amplitude/phase constellations. They also proposed an energy constraint method for amplitude/phase constellations. According to the minimum noncoherent distance for GLRT detection, we propose new energy control methods for two amplitude-level constellations to get better error performance than the original energy constraint method. We also propose three amplitude-level noncoherent coded modulation methods to further improve the error performance.
