DEVICE FOR COHERENT RECEPTION OF MULTIBEAM SIGNALS AND COHERENT DATA RECEIVER

摘要

FIELD: radio communication with mobile entities under urban conditions. SUBSTANCE: device for coherent reception of multibeam signal has search receiver and control unit; it functions to trace multibeam profile and time delay of beams. Coherent data receiver has simplified circuit arrangement due to taking filter, analog-to-digital converter, and carrier and clock frequency synthesizer out of it; this receiver shapes signal incorporating only cophasal component irrespective of phase difference of signal received. EFFECT: improved performance characteristics of radio receiving devices under urban conditions. 3 cl, 5 dwgw
