Abstract
The present disclosure relates to a wireless communication node comprising at least one array antenna configured to receive a radio signal, said array antenna comprising a plurality of receiving antenna devices, each of said antenna devices being connected to a respective receiving circuit which is configured for processing said radio signal. Each receiving circuit comprises a demodulator, an analog-to-digital converter and a decoder, the demodulator being configured to receive an analog signal from the corresponding receiving antenna device and to output a demodulated analog signal to said analog-to-digital converter which outputs a converted digital signal to the decoder. Furthermore, the node is configured for adding a direct current, DC, offset value to said demodulated analog signal wherein the combined offset values of said node follow a predetermined distribution of values, having a variance, over the analog-to-digital converters.
