Two block time - recursive algorithms are developed for the efficient and fast computation of the 1 - d rdgt coefficients and for the fast reconstruction of the original signal from the coefficients in both the critical sampling case and the oversampling case. the two algorithms are implemented respectively by a unified parallel lattice structure. and the computational complexity analysis and comparison show that the proposed algorithms provide a more efficient and faster method for the computation of the discrete gabor transforms
首先論證了一維rdgt系數求解演算法和由變換系數重建原信號演算法，不論是在臨界抽樣條件下還是在過抽樣條件下，都同樣具有塊時間遞歸特性，並提出了相應的塊時間遞歸演算法及其并行格型結構實現方法，計算機模擬驗證了并行格型結構實現的可行性，計算復雜性分析與比較也說明了rdgt塊時間遞歸演算法的并行格型結構在計算時間方面所具有的高速和高效性能。 -
Through the research and analysis of the advantages and disadvantages that exist in the domestic integrated business system and decision support system, this paper has pointed out the essential reasons that induced the information block in the middle - level, that is : business system in early stage is a kind of discrete system, it easily produces conflicts between enterprise structure and business system, and information easily block in the middle - level, therefore, the current business system may cause negative and passive effects on the decision - making
