用matlab仿真的灵巧噪声干扰，噪声干扰形式为线性调频信号卷积矩形脉冲串。(Smart noise simulation using matlab, noise in the form of a rectangular convolution chirp signal bursts.)

是一个关于OFDM仿真的小程序，比较小的程序，可以拿来练练手(It is a little on the OFDM simulation program is relatively small program that can be used to practice your hand)

仿真未编码和进行Hamming编码的QPSK调制通过AWGN信道后的误比特率性能(Hamming coding and for the simulation are not encoded by QPSK modulation in AWGN channel, the bit error rate performance)

说明：  单相光伏并网系统，逆变器采用dq下的PI控制。包含SIMULINK 2012-2018所有版本(For single-phase photovoltaic grid connected system, PI control under DQ is adopted for inverter. Include all versions of Simulink 2012-2018)
