COV gathers can also be constructed through selecting traces from different cross spreads of a 3D survey. A simple and practical way of constructing COV gathers can he described as that 1 when a dominant receiver line direction is determined, the inline offset and crossline offset of every trace can be calculated; 2 the inline offset and crossline offset ranges fruit; negative to positive for the whole dataset can be well represented by the range of the receiver spread of a typical source; 3 the full range of inline offsets can be divided into several sob ranges using twice the source line spacing and the full range of crossline offsets can be divided using twice the receiver line spacing; and 4 one sod; sob-range inline offset and one such sob-range crossline offsets form a COV gather.
一个简便实用的构造COV道集的方法是:在给定检波线的走向后,计算出每一地震道的inline炮检距和crossline炮检距;用观测系统中一个具有代表性的炮点的检波器排列范围来确定整个数据的inline炮检距范围和crossline炮检距范围,用两倍的炮线间距把inline炮检距的范围分成若干份,用两倍的检波线间距将crossline炮检距的范围也分成若干份,一份inline炮检距和一份crossline炮检距就构成一个炮检距向量道集。

As a differential detection is used between the intercarrier, the proposed algorithm overcome the high sensitivity to timing error of conventional algorithm and is robust to multi-path. The effect of sample frequency offset can't be ignored in a continuous OFDM system of a large number of subcarriers. The estimation precision of the conventional algorithm is low and the realization is complex. A joint estimation of sample frequency offset and fine frequency offset based on difference operation is proposed. As averaging use a large number of samples in a maximum likelihood algorithm, the estimation precision is very high. The use of difference operation cancel the effect of carrier frequency offset, and the proposed sampling frequency estimation algorithm is robust to carrier frequency offset.
最后,本文对连续系统中的采样频率和载波频率精同步技术进行较为深入的研究,由于子载波数目大的连续OFDM传输系统中,采样频率偏差不可忽视,以往的采样频率估计方法精度低、实现复杂,因此本文提出了一种基于差分处理的采样频率偏差和精载波频率偏差联合估计算法,利用了最大似然算法进行采样频率偏差的估计,由于采用了差分处理方法,消除了载波频率偏差对采样频率偏差估计的影响,采用的最大似然算法对大量样点进行平均化处理,所以,相对以往算法,提出的联合算法估计精度高,而且采样频率偏差估计对载波频率偏差具有鲁棒性。
