    摘要: A method in a network node comprises receiving a first input signal from a baseband processing unit of a first antenna branch, receiving a second input signal from a baseband processing unit of a second antenna branch, determining a first and second compensation coefficient, applying the first compensation coefficient to the second input signal to generate a first output signal, applying the second compensation coefficient to the first input signal to generate a second output signal, outputting the first output signal to a first power amplifier of the first antenna branch, the first output signal compensating for a mutual coupling from the second antenna branch to the first antenna branch, and outputting the second output signal to a second power amplifier of the second antenna branch, the second output signal compensating for a mutual coupling from the first antenna branch to the second antenna branch.
