摘要： In a communications system including a base station coupled to a transmission antenna by means of a transmission feeder cable, and coupled to a receiving antenna by means of a receiving feeder cable, a method and system for testing the antennas and feeder cables includes a testing apparatus located at or near the antenna end of the feeder cables. A processor located within the testing apparatus initiates tests in response to commands received from the base station by means of a digital interface, which preferably uses one or both feeder cables as a communications medium. The testing apparatus includes directional couplers for each of the feeder cables, and corresponding power detectors for measuring both forward (incident) and reverse (reflected) power. All test results may be sent back to the base station, by means of the digital interface, for further analysis and status reporting.

The testing apparatus includes directional couplers for each of the feeder cables, and corresponding power detectors for measuring both forward (incident) and reverse (reflected) power. A test tone generator places a known signal on the receiving feeder cable to enable the receiving antenna VSWR to be measured, as well as to transmit the test tone down to the base station for use in measurement of receiving feeder cable attenuation. On the transmission side, incident power of a known signal supplied by the base station to the transmission feeder cable may be measured by the transmission power detector at the top of the transmission feeder cable. Measuring the amount of power reflected back by the transmission antenna then enables determination of the transmission antenna VSWR. All test results may be sent back to the base station, by means of the digital interface, for further analysis and status reporting.

摘要： The invention relates to a method of compensating the dependence of the useful transmitter signal on the transfer function of a combiner filter in a mobile radio communication system. Before the useful transmitter signal is fed to the combiner filter it is filtered in the base band in connection with carrier frequency modulation with a filter, the total transfer function of which at least approximately comprises the inverted value of the transfer function of the combiner filter (COMB) transformed to the base band.
