代码说明：

communication system is expected to increase the service, the quality improvement and also the capacity, using spread spectrum communication system is one of the method to fulfill that demand. This quality and capacity factor will depend on the number of user. In order to see the performance of the Wiener Filter on the MC-CDMA system, simulation method is used by increasing the Direct Sequence Spread Spectrum CDMA signal, with digital modulation QPSK

Grid-connected photovoltaic (PV) inverters employ an islanding-detection functionality in order to determine the status of the electrical grid. In fact, the inverter must be stopped once the islanding operating mode is detected according to standards and grid-code limits. Diverse islanding-detection algorithms have been proposed in literature to cope with this safety requirement.

WSN_mac
wireless sensor networks are required to share one wireless channel among several sensor nodes. An efficient media access control (MAC) protocol must be developed and implemented on hardware. This MAC must be easily used by future users on the target hardware. The MAC should avoid data collision and posses strong speed of transmission.
