Abstract
In an exemplary embodiment, a vehicle includes antennas in proximity to one another; amplifiers; a computer memory; and a computer processor. The amplifiers are coupled to or part of the antennas. The computer memory stores a predetermined cases map that lists, for each of a plurality of combinations of frequencies for antennas, the predetermined cases map specifying, for each combination of frequencies, an amount of uplink RF power reduction required to reduce the degradation below a predetermined threshold. The computer processor is configured to retrieve, from the computer memory, the predetermined cases map; determine a current frequency combination for a current plurality of frequencies of the antennas of the vehicle; and provide instructions to one or more of the amplifiers to adjust a maximum RF power of one or more of the antennas, to thereby reduce receiver performance degradation between the antennas.
