Abstract:
Disclosed are a method and an apparatus for data transmission that apply a transmission diversity method which does not decrease transmission rate even when the number of transmission antennas is 3 or more for frequency division multiplexing scheme downlink cooperation communication to allow a terminal to have an excellent diversity characteristic.
Abstract:
Disclosed is an apparatus for transmitting multiple streams, including: a polarized wave control unit generating non-orthogonal polarization information for three or more input streams; a polarized wave generating unit polarizing three or more input streams in a baseband based on the non-orthogonal polarization information to generate vertical and horizontal polarization components; and a polarized wave transmitting unit transmitting the plurality of vertical and horizontal polarization components through dual polarization antennas.
Abstract:
Provided is a method for transmitting and receiving multi-input multi-output in a wireless backhaul network, including: selecting at least one pair of dual-polarized transmitting antennas to be activated among pairs of dual-polarized transmitting antennas of a transmitter; transmitting a signal through the selected pairs of dual-polarized transmitting antennas; and receiving, by pairs of dual-polarized receiving antennas of a receiver, the signal transmitted from the transmitter.
