Publication number: 20150341134Abstract: An exemplary embodiment of the present invention provides a method for a communication apparatus to process a signal. A first processor of the communication apparatus performs symbol mapping on a first baseband signal transmitted via a PDSCH (physical downlink shared channel). The first processor sends the mapped first baseband signal to a second processor of the communication apparatus by interfacing with the second processor. The second processor modulates the sent first baseband signal. The second processor converts the modulated first baseband signal into an intermediate frequency signal.Type: ApplicationFiled: March 23, 2015Publication date: November 26, 2015Applicant: Electronics and Telecommunications Research InstituteInventors: Chan Bok JEONG, Young Ha LEE, Pyeong Jung SONG
