The terminal device according to the present invention is a terminal device which receives radio signals that are space-multiplexed and on which non-linear pre-coding is performed, from a base station device including multiple antennas, the terminal device including: a channel state estimator 53 that estimates channel state information on a channel between the terminal device and the base station device; a terminal antenna module 51 that acquires a linear filter that is calculated in the base station device; and a channel equalization module 57 that performs channel equalization processing on the radio signals that are received at a first point in time, based on the channel state information at a second point in time that precedes the first point in time and on the linear filter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Terminal device, base station device, wireless communication system, reception method, and integrated circuit","description":"In a wireless communication system that performs non-linear pre-coding, degradation in transmission performance due to a feedback error is improved.
