Application of Conservative Power Theory for Active Power Filtering of Line-Commutated HVDC for Offhsore Wind Power

QAM调制软比特解调，能够更准确进行解调。(Soft bit QAM modulation and demodulation, can be more accurately demodulated.)

啁啾光栅matlab仿真程序，方便学习光栅特性(Chirped grating matlab simulation program to facilitate the learning Grating)

计算SENSE重建图像中的g-factor,这是并行磁共振成像SENSE算法的关键一步(G-factor is the metric to quantify the amplificaiton of noise power in reconstructing SENSE accelerated image. The detail was presented in Pruessmann s 1999 Magn. Reson. Med. paper. In theory, g-factor is the pixel-by-pixel ratio of the image variance between the SENSE reconstructed image and un-accelerated image. And g-factor depends on: (1) the k-space data trajectory (2) coil sensitivit profiles (3) noise covariance matrix of the array coil)

一个BP神经网络训练程序，经过训练，可用于模拟许多非线性问题。(A BP neural network training program, after training, can be used to simulate many nonlinear problems.)
