METHOD AND NODE RELATED TO CHANNEL ESTIMATION

A method comprises determining a first and a second sub-carrier associated with a channel, and multiplying a signal received on the first sub-carrier with a first number to form a first resulting signal. The first number multiplied with a known signal transmitted by a second transmitting node on the first sub-carrier equals a constant value. A signal received on the second sub-carrier is multiplied with a second number to form a second resulting signal. The second number multiplied with the known signal transmitted by the second transmitting node on the second sub-carrier equals the constant value. The second resulting signal is subtracted from the first resulting signal to obtain a signal for which interference from the second transmitting node is suppressed, and the channel is estimated based on the obtained signal.
