Disclosed are methods, circuit and devices for received signal noise reduction of cancellation. There is provided a first and a second antenna spatially separated from one another. A noise extractor may generate a signal indicative of noise received at the second antenna, and a channel estimator may estimate one or more parameters of a channel between the first and the second antennas. A filter may modify the signal indicative of noise received at the second antenna using the one or more estimated channel parameters to generate a signal estimating noise received at said first antenna. A signal subtracting module may subtract from a signal received at the first antenna the signal estimating noise received at said first antenna. |
