In contrast to other transmission techniques such as Linear Zero Forcing Beamforming (LZFB) or Interference Alignment (IA), BIA achieves a growth in Degrees of Freedom (DoF) without channel state information at the transmitter (CSIT). A real implementation based on Orthogonal Frequency Division Multiplexing (OFDM) and LTE parameters is implement on a testbed made up of a transmitter equipped with two antennas and two users equipped with a reconfigurable antenna each. Furthermore, a full CSIT technique such as LZFB is also implemented for comparison purposes. First, the theoretic achievable rates are obtained for both techniques. After that, the bit error rate of both schemes is evaluated regarding the achieved sum-thorughput.6application/pdfeng©2015 IEEELong Term EvolutionOFDM modulationArray signal processingError statisticsRadiofrequency interferenceCSIT techniqueBlind interference alignmentTransmission techniquesInterferenceSignal to noise ratioTransmitting antennasconference paperTelecomunicacionesopen access152015 IEEE 81st Vehicular Technology Conference (VTC Spring)CC/0000024022
