Title: RADIO SYSTEM AND METHOD FOR RELAYING RADIO SIGNALS WITH A POWER CALIBRATION OF TRANSMIT RADIO SIGNALS
Abstract:
The present invention provides a radio system (1) and a method (800) for relaying radio signals, providing a power calibration of transmit radio signals. With the radio system (1) and the method (800) no dedicated calibration signal generator is required for providing the power calibration of the transmit radio signals. The radio system (1) comprises at least one transmit path, a calibration unit (200) at the least one link (15-1, 15-2,...,15-N) and a power sensor (500). A selected one of coupled transmit signals (90-1, 90-2,..., 90-N) is forwarded to a power sensor (500, 500b) for measuring a power level of a portion (95) of the selected one of the coupled transmit signals (90-1, 90-2,..., 90-N), wherein the calibration unit (200) is adapted to update a power rating of the at least one transmit path (70-1, 70-2,..., 70-N) in response to the transmit power level of the selected one of the coupled transmit signals (90-1, 90-2,..., 90-N).
