By time-varying filtering, we realize the signal selectivity and interference suppression, especially for the signals with time-varying power spectrum. It is shown herein that conventional eigenstructure based methods are lower dimensional special case of the time-frequency subspace fitting method. The closed-form array response estimation algorithms for blind source separation in wireless communication is also developed in the dissertation by exploiting the data structure of second-order statistics of the array output in the presence of multipath. The proposed method achieves array response estimation with little constraint on signal property and propagation environment such as scatters or angular spread. Moreover, the array utilized here can be of arbitrary geometry and even uncalibrated. Since the closed-form solution is obtained, no misconvergency may occur and large amount of computation can be saved. The equivalent feed model and corresponding optimization designation are proposed to realize the downlink multi-user selective transmission. By coherent and non-coherent superposition of the electromagnetical field, multiple beams can be formed using a single array, so that each co-channel user signal is transmitted in each beam and will not interfered with each other. The proposed system scheme implements the digital beamforming and the channel allocation in the base band, therefore is suitable for the utilization of the radio software technology. The feasibility and effectiveness of the proposed model are proved by the RF experiment.

在窄带条件下，GSC－SSF方法还可以提高阵列的虚拟孔径，从而提高估计的性能；可以证明，Cyclic DOA 和SC-SSF方法可看作该方法的特例或近似； 3、提出了二维GSC－SSF方法和宽带谱相关DOA矩阵方法，利用信号的循环平稳特性解决了宽带条件下二维 DOA 估计问题，并具有阵元数少、计算量较小的特点； 4、提出了时频子空间拟合和宽带时频DOA估计算法，将联合时频分析的理论和方法引入到阵列信号的空间谱估计研究中，利用时变滤波实现信号选择性测向和干扰抑制，特别适合于谱时变信号；可以证明传统特征结构法可看作是时频子空间拟合方法的特例； 5、提出了多用户环境下阵列响应的估计方法——CARE方法，该方法对信号结构和传播参数（主要是散射源分布与角度散布）的约束较少，适用于各种几何结构的阵列甚至未校准的阵列，能够直接得到阵列响应的闭式解，因此计算量小、稳健性好，不存在收敛问题； 6、提出了针对多用户下行选择性发送的阵列等效激励模型、优化设计方法及其系统实现方案，通过空间场的相干叠加与非相干叠加使得单一阵列能够形成多个波束，并保证各波束内的用户信号各不相同且相互干扰最小；其系统方案具有在基带实现数字波束成形、信道分配并便于软件无线电实现的特点，其有效性已得到外场实测数据的证实。

The basin experienced three basin-forming cycles of Neopaleozoic, Mesozoic and Cenozoic Eras. Mesozoic fault and depression compounding basin composed the northern margin Jurassic petroleum system and the Cenozoic large-scale strike-slip and compressional basins composed the Tertiary petroleum system of the western Qaidam basin and Quaternary petroleum system of Sanhu. The intense tectogenesis of Yanshan and Xishan made the Jurassic petroleum system of the northern Qaidam more complex. The monocycle paleoclimate evolution in Cenozoic Era and multi-tectonic movement made the lake-basin evolution, hydrocarbon source-rock, reservoir development, accumulation condition and petroleum distribution are more exceptive in character and complex in feature.

There was a Letter of my Partner's, congratulating me very affectionately upon my being alive, giving me an Account how the Estate was improv'd, and what it produced a Year, with a Particular of the Number of Squares or Acres that it contained; how planted, how many Slaves there were upon it, and making two and twenty Crosses for Blessings, told me he had said so many Ave Marias to thank the Blessed Virgin that I was alive; inviting me very passionately to come over and take Possession of my own; and in the mean time to give him Orders to whom he should deliver my Effects, if I did not come my self; concluding with a hearty Tender of his Friendship, and that of his Family, and sent me, as a Present, seven fine Leopard's Skins, which he had it seems received from Africa, by some other Ship which he had sent thither, and who it seems had made a better Voyage than I: He sent me also five Chests of excellent Sweet-meats, and an hundred Pieces of Gold uncoin'd, not quite so large as Moidores.

他热情地邀请我去巴西收回我的产业。同时，他还要我给他指示，若我不能亲自去巴西，他应把我的财产交给什么人。在信的末尾，他又代表他本人和全家向我表示他们的深厚情谊，又送给我七张精致的豹皮作为礼物。这些豹皮是他派往非洲的另一艘船给他带回来的；他们那次航行，看来比我幸运得多了。另外，他还送了我五箱上好的蜜饯，一百枚没有铸过的金元，那些金元比葡萄牙金币略小些。

I sat in the large bare apartment in which I lived my junior and senior years (I had lived awhile in a sorority, the Tri Delt house, and had left it, typically, not over any issue but because I, the implacable "I", did not like living with sixty people) and I read Alburt Camus and Henry James and I watched a flowering plum come in and out of blossom and at night, most nights, I walked outside and looked up to where the cyclotron and bevatron glowed on the dark hillside, unspeakable mysteries which engaged me, in the style of my time, only personally.

我坐在我度过大三大四的又大又空的公寓里（我在集体宿舍住过一阵，又离开了，不是因为别的原因，而只是我，这个不可替代的&我&，不喜欢和六十个人住在一起），读着阿尔伯特&加缪和亨利&詹姆斯，看着一棵杏树花开花落；在许多晚间，我在外面散步，看着黑漆漆的山边分子加速器和回旋加速器的闪耀，一种不可言喻的神秘攫住了我，以我那个时代的方式，只是个人化的。

In my silver high-heel shoes,I go to take part in a belated dinner,I go through a tall wood in a rush,On the trees there are fantastic tropical fruits and clocks streamed with egg white,The sweet fragrance of those fruits seduces me,I pick off a beautiful dragon fruit,But see many white worms lying in it when cutting it,I scream and throw it on the ground,Those worms creep to me and begin to grow,I creep onto the tree,They also creep towards the tree wiggling their bodies,I remove my cumbrous high-heel shoes and voile skirt creeping towards a high place,like an agile cheetah,But strangely my small bag oppressively cumbers me,It turns out that the bag is full of pumpkins, monkey dolls with large mouths, crystal bottles and silver coins,I give all of these a vicious discard towards the ground from the tree,But those worms open their big mouths and swallow all of them greedily,Becoming more obese and uglier,I desperately creep upwards,Suddenly the moon is not so far from me,I jump on it with ease,Suddenly finding that the moon is a porous spongy body with the fragrance of the oven-fresh French stick bread,It takes me to flow away from that tree full of worms,I want to light a cigarette but ignite the sponge on the moon,So I descend from the height,Falling down to a huge birds' nest,In an instant my whole body is wrapped by a slick and white egg shell,I find myself becoming a new embryo,Crouching in the warm and ropy liquid,The world presents a color of delicate light yellow,In a vacuum-like silence,I hear my contented voice,"What a perfect world"

我穿着银色的高跟鞋，去参加一场迟到的晚餐，我匆忙地穿过一片高大的树林，树上挂满了奇妙的热带水果和流淌着蛋清的时钟，那些水果甜美的芳香诱惑了我，我摘下一颗漂亮的火龙果，切开来却看见里面躺满了白色的蠕虫，我尖叫着将它们丢在地上，那些蠕虫向我爬来并且开始生长，我爬到树上，蠕虫们也扭动身体朝树上爬来，我脱下了牵绊着我的高跟鞋和纱裙，象只敏捷的猎豹朝高处爬去，只是我的小包奇怪而沉重地拖累了我，原来包里装满了南瓜、大嘴猴玩偶、水晶杯子和银币，我将所有这些朝树下狠狠丢去，那些蠕虫却张开大嘴贪婪地将所有这些吞食下去，并因此变得更加肥大和丑陋，我拼命努力地向上爬，突然月亮就在我不远处了，我轻而易举地跳了上去，恍然发现月亮竟是一个带着刚出炉法棍香味的多孔海绵体，它带我慢慢飘离了蠕虫的树林，我想要点燃一支香烟却不小心引燃了月亮上的海棉，于是我从高处坠落啊坠落，落入一个巨大的鸟巢，顷刻间全身被光滑洁白的蛋壳所包住，我发现自己成为了一个暂新的胚胎，蜷缩在温暖粘稠的液体中，世界呈现出微妙的淡黄色，在真空般的静寂中，我听见自己满足的声音：&多完美的世界啊！&
