| Abstract(in English) | This paper describes an evaluation of a 16APSK RF signal Direct-Processing Transmitter and Receiver designed the purpose of smaller and more efficient. In the board, it was substantiated that the RF signal direct processing unit makes possible drastic scale reduction of the device as omitting IF signal processing part complexity, while keeping performance equal with existing digital communication technology for evaluation of 750 Mbps and 16APSK. An amplitude equalizer inserted inside avoids the degradation caused by the linear amplitude distortion at aliasing frequency range of sampling frequency response in L band. As a result we succeeded keeping good performance comparing with existing technology. |
