Abstract	The authors describe advanced techniques for designing demodulator VLSIs for digital radio communications, with particular application to satellite communication for TDMA (time division multiple access). The proposed demodulator design aggressively uses digital signal processing techniques to achieve fully digital circuitry. To realize stable and highly functional operation, the authors proposed and verified the following techniques: (1) orthogonal digital demodulating; (2) incoherent sampled carrier tracking and interpolation filter; and (3) burst detection and stabilization of recovery loops. These techniques were verified with hardware implementation of the demodulator VLSIs. The modulation scheme (binary or quadrature phase shift keying) and the operating mode (single carrier per channel or time division multiple access) can be remotely selected in the VLSIs.
