通过仿真,分析了多径效应和多普勒效应的原理.并给出了移动信道的建模方案和程序.每个结论都给出了仿真程序可直接运行.-through simulation, Analysis of the multi-path effects and the principle of Doppler effect. and gives the mobile channel modeling programs and procedures. Conclusion gave each a simulation program can run.

除了支持一般的小数运算，还支持常见的函数运算。 几个包中的MathFP是针对不同需要而提供的不同版本，开发J2ME只要使用net.jscience.math.MathFP就可以。-addition to general support for the fractional arithmetic, but also the common computing functions. Several packets of MathFP is different needs of the different versions, as long as the use of J2ME development net.jscience.math.MathFP can.

A. 产生一个长为1000的二进制随机序列，“0”的概率为0.8，”1”的概率为0.2；B. 对上述数据进行归零AMI编码，脉冲宽度为符号宽度的50%，波形采样率为符号率的8倍，画出前20个符号对应的波形（同时给出前20位信源序列）；C. 改用HDB3码，画出前20个符号对应的波形；D. 改用密勒码，画出前20个符号对应的波形；E. 分别对上述1000个符号的波形进行功率谱估计，画出功率谱；F. 改变信源“0”的概率，观察AMI码的功率谱变化情况；-have a length of 1,000 random binary sequence, "0" with a probability of 0.8, "a" with a probability of 0.2; B. above zero AMI data coding, and pulse width of symbols width of 50%, waveform sampling rate Symbol rate for the eight times that he painted before the 20 symbols corresponding waveforms (also given before 20 Source sequence); C. HDB3 code switch to depict the former 20 symbols corresponding waveform; D. Miller to switch codes to depict the former 20 symbols corresponding waveform; E. respectively above 1,000 symbols for the power spectrum waveform estimated to depict the power spectrum; F. Change source "0" the probability to observe AMI code changes in the power spectrum;
