OFDM
OFDM下行的仿真1、产生要传输随机数；
2、进行调制；
3、串并转换；
4、进行IFFT操作（代码中有用到共轭对称向量的IFFT为实数进行简化计算）；
5、增加循环前缀；
6、并串转换；
7、输出前滤波；
8、增加信道噪声（加性高斯白噪声）；
9、接收端串并转换；
10、去除循环前缀；
11、进行FFT变换；
12、信号解调；
13、误比特率计算；
(OFDM downlink simulation 1, have to be transmitted random number 2, the modulation 3 series and transforms 4, the IFFT operation (code useful to conjugate symmetric vector of the IFFT of real numbers to simplify calculations) 5, the increase in circulating prefix 6, and string conversion 7, the output before the filter 8, increased channel noise (additive white Gaussian noise) 9, the receiver string and conversion 10, removal of cyclic prefix 11, the FFT transform 12 , the signal demodulation 13, bit error rate )

BatchSimulation
As we know, the energy needed for sensors should be electrical. So the rst
step before start to work is to convert environmental energy to electrical one.
Inside the node there are dierent components for sensing the area, collecting
data and processing the data. So the main dierent part of this kind of nodes,
in compare of WSN nodes, is the power part. Once the stored energy reach
to a certain amount, the power supply for micro controller and transceiver will
start to work. They will continue to work until they have energy, as soon as the
energy nish, they stops and energy storage device start to work to save energy
again.
The other fact should be consider about EH-WSN node is that the available
energy can change in dierent nodes. So every node has its own harvesting rate.
