摘要： The impact of a fading dip in a radio channel on the communication between a first and a second antenna may be reduced by receiving a sounding signal at the first antenna or the second antenna over the radio channel and measuring the frequency response of the radio channel using this sound signal that was received. The radio frequency signal that is used to communicate between the first antenna and the second antenna is adjusted in response to the frequency response that was measured in order to reduce an impact of the fading dip in the radio channel on the radio frequency signal during operation. Related systems, methods, and devices are disclosed.

摘要： A wireless communication link arrangement and a method performed in the communication link, which link comprises a first node with a plurality of transmitting antenna arrangements and a second node with a plurality of receiving antenna arrangements that forms a number of radio chains RC, each arranged to operatively communicate a signal a comprising a data stream so as to form a primary MIMO-scheme. At least one of the nodes is arranged to control the degradation of the link by being configured to operatively: detect a malfunction for at least one radio chain RC of the primary MIMO-scheme, select a communication scheme using a reduced number of data streams communicated by the other radio chains of the link arrangement, communicate the selection of the communication scheme to the other node, and continue the communication according to a communication scheme.
