Abstract
An aspect of the present invention is a wireless communication system including an accommodation station device and a base station device connected to the accommodation station device through an optical transmission path and having n (n is an integer of 2 or more) antenna elements, wherein a plurality of optical signals having different wavelengths propagate through the optical transmission path, the wireless communication system including a prior information acquisition unit configured to execute prior information acquisition processing for acquiring, as prior information, dispersion phase difference information that is information including a dispersion phase difference that is a phase rotation amount difference generated between adjacent optical signals on a wavelength axis due to propagation of the optical signals through the optical transmission path, and a compensation phase shift unit configured to execute compensation phase shift processing for reducing a difference from a phase difference reference that is a predetermined reference on the basis of the prior information with respect to the phase rotation amount difference generated between adjacent optical signals on the wavelength axis caused by wavelength dispersion in the optical transmission line.
