Node and method for adjusting channel coefficients of a wireless channel

A computer program comprising instructions, which when executed by a processor, causes the processor to:

• obtain a calculated current correlation value between first channel coefficients estimated in a first time instant, and second channel coefficients estimated in a second time instant that is subsequent to the first time instant,
• obtain a previous correlation value calculated at a previous time instant, and
• determine a phase adjustment value based on an estimated phase difference to be applied to the estimated second channel coefficients associated with a wireless channel, which phase difference is estimated between a current correlation value and a previous correlation value.

A first node configured to adjust channel coefficients of a wireless channel between the first node and a second node in a wireless communications network, the first node further being configured to:

• obtain a calculated current correlation value between the first channel coefficients estimated in a first time instant, and the second channel coefficients estimated in a second time instant, that is subsequent to the first time instant,
• obtain a previous correlation value calculated at a previous time instant, and
• determine a phase adjustment value based on an estimated phase difference to be applied to the estimated second channel coefficients associated with the wireless channel, which phase difference is adapted to be estimated between the current correlation value and the previous correlation value.
