Abstract
A receiver () featuring a distributed antenna combining system performs two stages of antenna combining. An antenna array () receives () L streams, or information flows, from UEs (), and outputs antenna signals on N antenna ports. N parallel radio receivers () frequency convert () the N received signals to baseband. A first antenna combining circuit () applies () a relatively low-complexity form of antenna combining (e.g., MRC) to the N radio signals to generate K streams of virtual information. A second antenna combining circuit () applies () a relative high-complexity form of antenna combining (e.g., IRC) to the K virtual streams to generate L information streams. In one embodiment, antenna elements may have different polarization directions, and the first antenna combining circuit () generates two, differently-polarized virtual information streams for each UE () stream.
