2. In signal space , speech enhancement is adopted to effectively suppress the noise and increase the discriminative information embedded in noisy speech signal . however , the speech distortion introduced by enhancement , as well as the residual noise , is a very adverse factor for recognition
   在信號空間，利用語音增強有效抑制噪聲，提高輸入信號中的鑒別信息，但增強帶來的語音失真和增強后的剩余噪聲是對語音識別非常不利的因素。
3. An algorithm for matching the esprit ' s estimation of two - dimensional angle by using twice svd and once schur is proposed . using two row uniformity sensor - arrays and adding one sensor , the algorithm decomposes the array twice and exploits rotational invariance properties of signal space , so that both angles may be computed via matrix pencil method , and these estimates are automatically paired . simulation results are presented to verify the efficacy of the proposed algorithm
   首先針對esprit算法對窄帶源進行二維doa估計存在測向冗余的情況，提出了一種改進算法，該算法利用子陣信號數(shù)據(jù)矩陣中包含的信號空間的旋轉(zhuǎn)不變性質(zhì)，借助于矩陣束方法求解出信號的二維到達角，并且利用兩次奇異值及一次schur分解從而實現(xiàn)了esprit二維doa估計參量的自動配對； 2
