WIPO Patent Application WO/2016/155548

A1

The present invention relates to an electronic device in a wireless communications system, the wireless communications system, and a method. The electronic device according to the present invention comprises: a reception unit, configured to receive a signal from another electronic device in a wireless communications system; an analysis filtering unit, configured to set an analysis filter group according to a parameter of a non-perfect reconstruction filter group, decompose, by using the analysis filter group, signals received by the reception unit into multiple paths of sub-band signals and perform analysis filtering; and an interference cancellation unit, configured to, for each path of sub-band signals among multiple paths of sub-band signals, cancel inter-band interference in each path of sub-band signals according to each path of sub-band signals and neighboring sub-band signals thereof. By using the electronic device, the wireless communications system and the method in the present invention, any filter design method can be used; only frequency band division requirements need to be satisfied, and a filter can be designed without requiring strictly complying with a perfect reconstruction feature, thereby greatly improving the design flexibility of the wireless communications system.
