Interference suppression in aerial-staying communication relay apparatus
The granted patent (Publication Number: US11973573B2) discloses an aerial-staying type communication relay apparatus with a repeater-type relay communication station and plural antennas for feeder link. The apparatus includes a feeder-link communication section for transmitting and receiving relay signals to and from plural gateway stations via plural antennas for feeder link. An interference suppression section is incorporated to suppress interference between feeder links formed with the plural gateway stations. This section comprises means for retrieving pilot reception signals, estimating path differences, obtaining correction values, estimating propagation path response, calculating reception weights, and applying these weights to reception signals received via the antennas for feeder link.
Furthermore, the interference suppression section calculates and stores reception weights and transmission weights for each of the plural gateway stations based on the estimation result of the propagation path response. These weights are then applied to reception signals received via the antennas for feeder link and to transmission signals to be transmitted via the same antennas. The patent also includes an interference suppression method and a system comprising the communication relay apparatus and plural time-synchronized gateway stations. The method involves retrieving pilot reception signals, estimating path differences, obtaining correction values, estimating propagation path response, calculating and storing reception weights, and applying these weights to reception signals. The system includes plural gateway stations transmitting and receiving relay signals on the same frequency in a feeder link to and from the relay communication station of the aerial-staying type communication relay apparatus.
