This paper describes the implementation of technique based on D–BLAST spatial multiplexing over Software Defined Radio (SDR) equipment; specifically, using Universal Software Peripheral Radio (USRP) Ettus Research x310; with the aim of solve the problem of spatial diversity that the MIMO Alamouti scheme has, since it is not possible to increase the number of antennas of the transmitter with respect to the receiver. The simulation scenario was in an indoor environment using graphical programming tools with the Labview Communications Software, achieving a more robust coding design based on the nonlinearity of matrix equations, in this way, the effects of interference were mitigating through the redundancy of information due to the increase of the antennas at the transmitter. The experimental results evaluated were bit error rate (BER) and symbol error rate (SER) to determine the effectiveness of spatial diversity. The gain achieved was around 10dB and 7dB in MIMO 2×2 and MIMO 3×2 respectively, using the symmetric D–BLAST technique.
