| Popis: | A two-stage Doppler-phasor correction algorithm for mobile satellite, DSP-based modems is presented. The modulation considered is trellis-coded, differential phase-shift keying (DPSK) involving eight signal points. The Doppler phasor rather than the Doppler frequency is corrected as it leads to easy realization in DSP-based software. The Doppler phasor correction algorithm that is presented has a setup mode where the data are known and a data mode where the data are unknown. As such, it is intended for stream data or digital speech transmission. Both computer simulation and analytical techniques are used in the performance analysis. > |
