3. 2. Generalized Bandpass Sampling Receivers for Software Defined Radio

   Författare :Yi-Ran Sun; Svante Signell; Markku K. Renfors; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radio receivers; Software Defined Radio SDR ; uniform nonuniform sampling; reconstruction; bandpass sampling; noise aliasing; sampling jitter; generalized bandpass sampling; complex signal processing; complex FIR and IIR filter design; Switched-Capacitor SC circuit; Electrical engineering; Elektroteknik;

   Sammanfattning : Based on different sampling theorem, for example classic Shannon’s sampling theorem and Papoulis’ generalized sampling theorem, signals are processed by the sampling devices without loss of information. As an interface between radio receiver front-ends and digital signal processing blocks, sampling devices play a dominant role in digital radio communications. LÄS MER
