As the signal is shifted from the original center frequency, the RF power analyzer reads lower and lower power levels as more and more of the signal shifts out of the intended transmission channel.
当信号从原中心频率偏移，信号越来越从设定的发射通道偏移，功率分析仪的功率电平会越来越低。
The power line channel noise is simulated by MATLAB and the attenuation is simulated through the channel transmission module of FIR filter.
利用MATLAB及用fir滤波器做信道的传输函数模型对信道噪声和复衰减特性分别进行了建模。
The proposed algorithm reduced the interference to improve the spatial reuse of the channel by adjusting the transmission power of each node, which would give rise to the improved network throughput.
在形成网络拓扑之后，算法通过调整节点的传输功率到一个合理水平来降低干扰，从而提高信道的空间复用度以优化网络的吞吐量。
