分析比較了波束域處理與陣元域處理的分辨能力以及估計性能，并從降低分辨門限和估計方差角度考慮，給出了轉(zhuǎn)換矩陣的構(gòu)造方法。 - Tricepstrum equalization algorithm ( btea ) and super - exponential ( se ) algorithm based on block data estimation is studied , and these algorithms use hos explicitly . their performance , such as estimation variance and bias , is analyzed . a kind of sparse cross cumulant and sparse equalizer is proposed to simplify the se algorithm , and the simulating results show efficient reduction in complication
?研究了幾種直接使用高階統(tǒng)計量的算法，包括基于數(shù)據(jù)段估計的倒三譜算法和超指數(shù)算法，分析了算法的估計方差和偏差等性能；由于超指數(shù)算法計算量較大，不利于實(shí)時均衡，利用水聲信道的稀疏性，提出了一種基于稀疏互四階累積量和稀疏權(quán)的算法，有效降低了超指數(shù)算法的計算量。
