单相逆变并网电路的主电路与控制电路的 simulink 拓扑结构图， 主电路由直流源、 mosfet 全桥、 LC 无源滤波器、 负载 R1、 R2 组成， 其中 R1 为 恒定负载， R2 为仿真负载突变并入的。 控制电路为 SPWM 闭环调制， 通过检测输出端的电压有效值通过 PI 控制器反 馈回控制端使输出电压尽可能为一个优质的正弦波且有效值在 220V 左右， 频率 为 50Hz， 根据相关准则输出电压波形 THD 应在 5%以内。(The Simulink topology of the main circuit and the control circuit of the single-phase inverter grid connected circuit, The main circuit is composed of DC source, MOSFET full bridge, LC passive filter, load R1 and R2, wherein R1 is The constant load, R2, is incorporated into the simulation load mutation. The control circuit is SPWM closed loop modulation, and the effective value of the output voltage is detected through the PI controller The feed back control makes the output voltage as high as possible a sine wave, and the effective value is about 220V, frequency For 50Hz, the output voltage waveform THD shall be within 5%, according to the relevant guidelines.)

WLAN仿真－发送机 wlan No Comments 设置完系统参数后，开始产生发送数据。 1. 产生随机的发送bit（tx_bits），这里不考虑信道编码。 2. QAM映射 3. 将数据映射到不同载波，形成OFDM符号 4. 产生pilot，并将pilot插入OFDM符号中 5. 加入dc和guard子载波 6. 进行ifft，将频域信号变到时域，并加入循环前缀 7. 对信号进行overlap window 8. 在时域产生short preamble 9. 在时域产生long preamble 10. 将preamble和数据符号组成packet 11. 升采样 得到信道传输的数据Tx_signal_up 具体程序见附件 wlan_transmitter.m-WLAN Simulation- wlan No Comments transmitter system parameters set finished, the beginning to have to send data. 1. Have sent random bit (tx_bits), here does not consider channel coding. 2. QAM mapping 3. The data is mapped to a different carrier to form OFDM symbols 4. Have a pilot, and pilot inserted OFDM symbols 5. Adding dc and guard subcarriers 6. To carry out ifft, will change the frequency domain signal to time domain, and add cyclic prefix 7. the signals overlap window8. In the time domain have a short preamble9. In the time domain have a long preamble10. the preamble and data symbols packet11. or sampling re
