In this work we present a Multiple-Input Multiple-Output (MIMO) implementation based on Orthogonal Frequency Division Multiplexing (OFDM) made up of a transmitter with 4 antennas and 2 users equipped with 2 antennas each one, which allows us to evaluate the performance of BD in indoor scenarios. First, the theoretic achievable rates are obtained for the measured channel in an offline evaluation. After that, the bit error rate performance is evaluated regarding the system sum throughput. To the best of our knowledge, this is the first time that BD performance is validated using a multiuser MIMO testbed.5application/pdfeng© 2014 IEEEMultiple-Input Multiple Output (MIMO) testbedOrthogonal Frequency Division Multiplexing (OFDM)interference channelblock diagonalization (BD)conference paperTelecomunicacionesopen access15European Signal Processing Conference EUSIPCO 2013CC/0000021486
