BIDIRECTIONAL RELAY STATION SYSTEM USING SPACE FREQUENCY BLOCK CODING AND PHYSICAL NETWORK CODING AND METHOD THEREOF

摘要

The present invention relates to a bidirectional station system and a method thereof. According to the present invention, physical network coding (PNC) and a bidirectional transmission scheme of two steps wherein user terminals perform transmission at the same time by using SFBC technology are applied. Therefore, both time efficiency of PNC and diversity of SFBC can be obtained in a circumstance where acquisition of a feedback path is difficult or acquisition of channel information is difficult as reversibility is not reliable. The method of the bidirectional station system includes a multi-connection step, a coding step, and a broadcast step.;COPYRIGHT KIPO 2016
