单相逆变器并网控制，单相逆变器并网控制，单相逆变器并网控制(Single-phase inverter grid-controlled, single-phase inverter grid-controlled, single-phase inverter and network control)

说明：  多输入多输出(Multiple-Input Multiple-Output)技术是无线移动通信领域智能天线技术的重大突破。该技术能在不增加带宽的情况下成倍地提高通信系统的容量和频谱利用率，是新一代移动通信系统必须采用的关键技术。(Multiple input multiple output (MIMO) technology is a major breakthrough of smart antenna technology in the field of wireless mobile communication. This technology can double the capacity and spectrum efficiency of the communication system without increasing the bandwidth. It is a key technology that must be adopted in the new generation of mobile communication system.)

LDPC校验矩阵生成、高斯消去法编码、BP译码程序，可以作为自己编写LDPC编译码程序的参考。因为matlab代码效率不高，所以这个程序仿真起来比较慢.(LDPC check matrix generation, Gaussian elimination coding, BP decoding procedure can be used as its own procedures for the preparation of LDPC codec reference. Because matlab code efficiency is not high, so this process is relatively slow simulation together.)

说明：  2. 关于无线信道的多普勒谱，请回答以下问题： (1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请描述产生混叠的各种原因； (2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理； (3) 请用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请描述：自己用计算机产生的经典谱是正确的依据。(2. Regarding the doppler spectrum of the wireless channel, please answer the following questions: (1) in some wireless channels, doppler frequency shift will cause aliasing of the output signals of the wireless channel.Describe the various causes of aliasing; (2) there is a classic spectrum in the doppler spectrum in the wireless channel, please explain the mechanism of producing this spectrum shape; (3) please use Simulink tool to write code (s-function mode) to generate a single-path Rayleigh channel, whose doppler spectrum is the classical spectrum, in which the moving rate is 120km/h.And please describe: your own computer generated classical spectrum is the correct basis.)
