摘要:
A hybrid combining method in a receiver (200) is provided, and the method includes that wideband combining, e.g. using a maximum ratio combining (MRC) or an interference rejection combing (IRC) process, to combine signals distributed over a first plurality of subcarrier frequencies from antennas (202) in the same polarization direction is performed, resulting in a combine signal for each polarization direction that is distributed over a smaller number of subcarrier frequencies, then a two-port narrowband IRC is done of these wideband combined signals for the two polarization directions, resulting in a diversity combined signal.
