Examples
- Shortwave channel is time varying transmission channel . it has dispersion in frequency and time domains . this characteristics hinds the data transmi - ssion at high speed and the correction of received data . in this dissertation i have analyzed the statistic characteristic of shortwa - ve channel , established the model of shortwave channel and simulated the rayl eigh fading distribution . the technology of spreading spetrum has been proved that it has the capability for anti - multipath and discerning multipath
在短波通信中，由于信道的时间色散和频率色散，引起多径展宽和多径衰落，前者限制了数据的传输速率，后者造成短波数据通信中出现突发错误，为了解决多径效应对短波通信的影响，本文所做工作如下：首先详细分析了短波信道的统计特性，建立其数学模型；其次分析了扩频通信的特点，从理论上证明扩频技术不仅具有抗多径干扰能力，而且具有分离多径的能力；介绍了传统的rake分集合并技术的特点。 - According to the calculation formula of the ratio of pile and soil of compound foundation bearing capacity , and base on the calculation formula of the ratio of pile and soil given in this thesis , the relation model of rayl eigh wave velocity and gravel pile compound foundation bearing capacity is deduced
根据复合地基承载力应力比计算公式，基于本文提出的应力比计算模型的基础上推导了瑞雷波速和碎石桩复合地基承载力之间的关系模型，建立了日本模型、武汉地区模型、下辽河平原模型三种模型的碎石桩复合地基承载力计算公式。
