matlab-0-1Knapsack-problem-PSO

利用matlab软件设计并仿真下面的无线通信系统。模拟信源为单音频信号。模拟调制方式为DSB。信道为多径信道（仿真中2径），信道中噪声为加性高斯白噪声。采用相干解调接收。画出了解调器输出端性能曲线与点信噪比SNR的关系。 (Software design and simulation using matlab the following wireless communication systems. A single analog audio signal source. Analog modulation of DSB. Channel multi-path channel (simulation 2 diameter), channel noise is additive white Gaussian noise. The use of coherent demodulation receiver. Draw the output of the demodulation performance curve and the point of the relationship between signal to noise ratio SNR.)

光伏并网，蓄电池储能双向DCDC，能正常运行，采用PQ控制(PVarray_grid_connected，running perfectly)

说明：  能够根据已知参数计算同步时钟系统的预期寿命。考虑了多个切换器，考虑了节点损坏后只作为从节点、只作为主节点、总线阻塞等情况。(The expected life of synchronous clock system can be calculated according to the known parameters. Several switchers are considered. The node is only used as slave node, only as master node, and bus is blocked.)
