   摘要提出了一種適用于慢變通道的雙碼率tcm - qam系統(tǒng)方案，該方案有較高的編碼增益，同時(shí)滿足90旋轉(zhuǎn)不變要求。
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(qiáng)有效抑制噪聲，提高輸入信號中的鑒別信息，但增強(qiáng)帶來的語音失真和增強(qiáng)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(jìn)行二維doa估計(jì)存在測向冗余的情況，提出了一種改進(jìn)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(dá)角，并且利用兩次奇異值及一次schur分解從而實(shí)現(xiàn)了esprit二維doa估計(jì)參量的自動(dòng)配對； 2
