Wireless Sensor Networks (WSN) is different than the Cellular Networks as I mentioned earlier. A WSN is composed of a large number of sensor nodes that communicate using a wireless medium (air). The sensor nodes are deployed randomly in the envir

matlab实现的OFDM运用于ROF光纤无线通信系统的仿真，用的是4QAM调制，LS信道估计，还包括Optisystem的仿真，是毕设的仿真，非常珍贵。,matlab achieve ROF optical fiber used in the OFDM wireless communication system simulation, using 4QAM modulation, LS channel estimation, the simulation also includes Optis
