摘要： The present solution relates to a method in a communication node (115) in a wireless communication system (100) for improving signal handling. The communication node (115) is arranged to receive signals from the at least one antenna (120). First, a frequency domain conversion is executed (201) for each antenna signal. The frequency domain conversion is done by receiving (201a) a continuous signal from one of the at least one antenna (120), splitting (201b) the continuous antenna signal into windowed signals, and by performing (201e) a frequency domain conversion of the windowed signals. Then, a channel estimate based on a frequency converted pilot signal is provided (202). Providing (202) the channel estimate is performed by extracting (202a) a pilot signal, splitting (202b) the pilot signal into windowed signals, performing (202d) a frequency domain conversion of the split pilot signal; and then by providing (202e) a channel estimate of the frequency converted pilot signal. Thirdly, diversity combined signals are provided (203) by performing (203a) diversity combining based on the frequency converted windowed signals and the channel estimate, and by combining (203c) the diversity combined signals.
