1、In Figure 4 we plot the finish times for each node.The minimum possible finish time in this experiment is equal to 25 rounds.Observe that without coding the average finish time is roughly three times longer compared to using network coding.
2、Mathematically,Hartley's law is stated as I∞B×t,where I= information capacity,B= system bandwidth (Hz),t= transmission time (second).This equation shows that information capacity is a linear function and directly proportional to both system bandwidth and transmission time.
3、Modern communication systems use digital modulation techniques.Advancements in very large integration (VLSI) and digital signal processing (DSP) technology have made digital modulation less cost than analog transmission systems.Digital modulation offers many advantages over analog modulation.
4、In 1948,C.E.Shannon (also of Bell Telephone Laboratories) published a paper in the Bell System Technical Journal relating the information capacity of a communications channel in bits-per-second (bps) to bandwidth and signal-to-noise ratio.Mathematically stated,the Shannon limit for information capacity is
where I= information capacity (bps),B= bandwidth (Hz),S/N= signal-to-noise power ratio (unit-less).

1、在图4中,我们绘制每个节点的完成时间.可能的最小完成时间在这个实验中,等于25轮.观察到的未编码的平均完成时间大约是三倍相比,使用网络编码.2、数学,哈特利的法律规定为我∞B×T,在那里我=信息容量,B =系统带宽（赫兹）,T =传输时间（秒）.该方程表明,信息量是一个线性函数和对系统的带宽和传输时间成正比.3、现代通信系统使用的数字调制技术.超大规模集成（VLSI）技术和数字信号处理（DSP）技术取得了比模拟传输系统的低成本数字调制.数字调制比模拟调制有许多优点.4、1948,C.E.Shannon（也是贝尔电话实验室）发表了一篇论文,在贝尔系统技术期刊涉及每秒一个通信信道的信息容量（BPS）带宽和信噪比.数学上表示,香农极限的信息容量就是我=信息容量（BPS）,B =带宽（赫兹）,S / N =信号-噪声功率比（单位少）.
