The result of whole-time-domain processing and analysis of all the data from 70 stations and 121 sets of observation data in Gansu-Ningxia-Qinghai area shows that most of the conditional probabilities (credibilities) of monomial short - impending anomaly correspondent earthquake are comparatively low. The level of prediction can be only improved by using proper comprehensive prediction methods. Three kinds of comprehensive analysis and prediction methods are given after research.

The result of whole-time-domain processing and analysis of all the data from 70 stations and 121 sets of observation data in Gansu-Ningxia-Qinghai area shows that most of the conditional probabilities (credibilities) of monomial short - impending anomaly correspondent earthquake are comparatively low. The level of prediction can be only improved by using proper comprehensive prediction methods. Three kinds of comprehensive analysis and prediction methods are given after research. They are "method of directly calculating precursory information content", "multi-factor comprehensive correspondence analysis method"and "information synthesis method". Among them, the first one is better for practical use.

对甘、宁、青三省区70个台站,121个测项自正式观测以来的全部资料进行了整个时间域的处理分析,结果表明单测项短临异常对应地震的条件概率(信度)大多数是比较低的,只有采用适当的综合预报方法才能有效地提高预报水平。通过深入研究提出了三种综合分析预报方法,即“前兆信息量直接计算法”,“多因子综合相关分析法”及“信息合成法”,其中以“前兆信息量直接计算法”普适性、可操作性更好一些。

The studies of the predecessors showed that current isotropic and anisotropic migrated imaging theories are difficult in effectively eliminate the in- fluence of anisotropie faulted belts, for example, the issue of smeared imaging for faulted zone (shadow area) can he often met in prestaek depth migration processing. For that reason, the paper carried out appreciated study of effects of wide/ narrow azimuth survey by using 3-D full-azimuth seismic data acquired on piedmont fracture belts of Tulufan Basin in the west of China and taking fracture belts and its relevant fractured reservoir as exploration targets. The data processing in the study was ordinary processing in time domain with relative amplitude reservation. It is considered through analyzing the differences between seismic at tributes information such as stack sections with different azimuth angles, gathers with same CDP analyzed points and coherent data volume in different azimuths that in a condition of comparatively plain strata ,relative simple velocity fields and hav ing certain signal to-noise ratio, using wide azimuth (aspect is greater than 0. 5) survey can obtain better imaging results of multi oriental minor faults than by narrow azimuth survey in developed fracture belts and can also obtain more distinct faulted zone and spatial scope of reservoir at the same time.

前人的研究表明,现有的各向同性和各向异性偏移成像理论,均难以有效地消除各向异性断裂带的影响,如在叠前深度偏移处理中经常会遇到断裂带成像模糊(阴影带)问题。为此本文针对在中国西部吐鲁番盆地山前断裂带采集的全方位角三维地震勘探数据,以断裂带及其相关的裂缝性储层为勘探目标开展了宽/窄方位角观测效果评价研究。研究中对数据采用相对保持振幅的常规时间域处理。通过分析不同方位角观测的叠加剖面、相同CDP分析点道集、相干数据体等地震属性信息之间的差异后认为:在地层相对比较平坦、速度场相对简单和具有一定信噪比的条件下,对于断裂较为发育的地区而言,采用宽方位角(纵横比大于0.5)勘探比窄方位角可获得更好的多方向小断层的成像效果,同时可以获得较清晰的断裂带及其储层的空间范围。

>=In this paper, a space-time processing receiver for WCDMA is presented for the uplink over the Gaussian channel and frequency selective Rayleigh fading channel.

The conventional RAKE receiver and 2D RAKE receiver are compared the space-time processing receiver we presented in this paper as well. The simulation shows that the presented receiver is a better choice.

本文针对处于加性高斯白噪声和频率选择性多径衰落信道下的WCDMA系统,提出一种空时处理的接收方案。在空间处理部分,采用基于LMS自适应算法的自适应阵列;在时间域处理采用2步并行干扰对消的多用户检测算法。在多用户检测算法方面我们也与去相关算法和LMMSE多用户检测算法进行了比较,同时,我们也用该系统与传统的RAKE接收以及采用天线阵的2维RAKE接收的误码性能进行了比较,仿真表明,自适应阵列与2步并行干扰对削多用户检测算法相结合的方案是较好的选择。
