Abstract:
1. A multi-antenna signal receiving device, comprising: at least two antennas configured to receive at least one stream, a received signal of a first antenna including components corresponding to a plurality of first paths and a received signal of a second antenna including components corresponding to a plurality of second paths; a first detector configured to detect a component corresponding to a first path of the plurality of first paths from among components included in the received signal of the first antenna, to detect a component corresponding to a second path of the plurality of second paths from among components included in the received signal of the second antenna, to remove a multi-path interference in the received signal using at least one stream detected from a prior iteration, and to extract the component corresponding to the first path from among the components in the received signal of the first antenna; a second detector configured to detect a component corresponding to the remaining first paths of the plurality of first paths from among the components included in the received signal of the first antenna, and to detect a component corresponding to the remaining second paths of the plurality of second paths from among the components included in the received signal of the second antenna; and a combining device configured to combine the detected components from the first detector and the detected components from the second detector, to detect the at least one stream.
