System of transmit antennas adapted to propagation conditions for radio broadcasting |
摘要 |
To broadcast synchronized radio waves in at least one frequency band in a predetermined territory, antennas (AS, ATI, AE) emit waves to respective coverage areas in which receivers (RQ, RB) measure characteristics of the emitted waves and transmit to a central server (SC) . The server analyzes the characteristics (CO) as a function of prediction models for broadcasting waves in the territory in order to determine adjustment parameters for the antennas. The server transmits the adjustment parameters to the antennas to control them in order to offer a greater diversity of radio broadcasting services and to optimize coverage areas according to different wave propagation modes. |
