说明：  OFDM系统中基于LS 和 MMSE 的信道估计(OFDM Systems Based on LS and MMSE channel estimation)

power_svpwm_multiPhasesLevel.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_svpwm_multiPhasesLevel.rar, Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

经典的信息论准则估计信号源个数。 使用空间谱估计理论，模拟发射信号由天线阵列接受采样。经过AIC和MDL两种算法，估计出采样序列中信号的个数，所加噪声是白噪声。(Classical information theory for sources number estimation. It s spatial spectrum estimation theory. it analogs transmission signal from the antenna array . It uses two algorithms“ AIC and MDL ”to estimate the number of sampled signal sequence. the added noise is white noise.)

程序目的 在kc处各放置一个高斯脉冲源hy 在(kc-1)处放置另一个高斯脉冲源(-hy)(Procedures aimed at kc Department placed a Gaussian pulse source hy in (kc-1) Department to place another source of Gaussian pulse (-hy))
