MIMO-OFDM Wireless Communications with MATLAB

基于OFDM的matlab仿真，内含文字说明(Based on the OFDM matlab simulation, containing text description)

基于差分进化算法的pid参数优化，包括性能指标(PID parameter optimization based on differential evolution algorithm, including performance indicators)

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)
