The WCDMA network shares system bandwidth, and is a self-interfering system. The WCDMA network planning should consider the interference control in addition to network coverage. Therefore, it requires more precise propagation models in contrast with the GSM network planning. The WCDMA network supports multiple services, and its support of high-speed services makes the WCDMA network cell coverage smaller and the coverage radius is only hundreds of meters or less. For the dense urban environment, in such small coverage radius, the electric wave propagation paths from the transmitter to the receiver include direct wave, reflective wave on the vertical surface of the building, diffractive waves on the vertical edge of the building, and the diffractive waves on the horizontal edges of the building, and the high-order reflective/diffractive waves (the influence of second-order reflective/diffractive waves is significant), as shown in Figure 1. Therefore, the features and distribution of the buildings are critical to the signal propagation, and affect the receiving signal strength significantly.
WCDMA网络是共享系统带宽的，是一个自干扰系统，因此WCDMA网络规划不仅需要考虑网络覆盖，还要考虑干扰控制，因此相对于GSM网络规划需要更加精确的传播模型；同时WCDMA网络支持多种业务，对高速数据业务的支持使得WCDMA网络小区的覆盖范围较小，半径仅为几百米甚至更小，对于密集城区环境中这样小的半径内，从发射机到接收机的主要电波传播路径包括直射波、在建筑物垂直面上的反射波、在建筑物垂直棱上的衍射波、在建筑物水平棱上的衍射波以及高阶的反射/衍射波(其中二阶反射/衍射波的影响相当大)，如下面图1所示，可见建筑物的特征和分布对信号传播起着关键作用，对接收信号强度有着十分重要的影响。

The degree of retardation of oxygen precipitation was different by n-type heavily dopants. On the condition of the same concentration of dopants and oxygen in heavily doped Cz-si, dopant of As had stronger retardation-3-than dopant of P.(3) The morphology of induced defects by oxygen precipitate in heavily doped Cz-si was affected by n-type dopants. Stacking faults were observed in heavily P-doped Cz-siliocn, but dislocation loops were observed in heavily As-doped Cz-si. Because of that the nucleation critical radius of oxygen precipitate in heavily doped Cz-si is affected by dopants, combined with free-electron effect and dopant-intrinsic point defect interaction, there are reverse influence on oxygen precipitation in heavily doped Cz-si between p-type and n-type dopants. Owing to the covalent radii effect of dopant, the degree of retardation of oxygen pricipitation and the morphology of induced defects by oxygen precipitates are not same among n-type heavily P-doped Cz-si.2. With different nucleation annealing, the behavior of oxygen precipitates and induced defcts in heavily As-doped Cz-si after two step Lo-Hi temperature annealing was investigated.

Heavily dopant of As retarded not only the nucleation but also the growth of oxygen precipitation, and dislocation loops was observed.(2) oxygen precipitation behavior in heavily doped Cz-si wafers wer
