The differences on resolution capability and the performance of estimation between beam - space processing and element - space processing are analyzed . transforming matrices are designed for the consideration of depressing the resolution threshold and estimation variance
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(jì)性能，并從降低分辨門(mén)限和估計(jì)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(jì)量的算法，包括基于數(shù)據(jù)段估計(jì)的倒三譜算法和超指數(shù)算法，分析了算法的估計(jì)方差和偏差等性能；由于超指數(shù)算法計(jì)算量較大，不利于實(shí)時(shí)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(jì)算量。
