A cyclo-stationary complex multichannel wiener filter for the prediction of wind speed and direction [PDF]
, 2013 This paper develops a linear predictor for application to wind speed and direction forecasting in time and across different sites. The wind speed and direction are modelled via the magnitude and phase of a complex-valued time-series.
