The project is based on the MIMO technology (Multiple antennas in the transmitter and receiver) that can exploit the dispersion of the channel since multiple links are created on the same radio band, besides improving the speed of data transmission by multiplexing and the reliability of the system due to the diversity of antennas; in this research, a 4x4 MIMO wireless communications system is simulated and implemented with the V-BLAST algorithm (Bell-Laboratories vertical space-time architecture)
Here is one of the solutions for future wireless networks in which MIMO systems are used, improving the quality of communication through the V-BLAST algorithm by improves the transmission speed, since this produces cancellation of interference in the transmission of data. To do this, by simulation with MATLAB and implementation with LabVIEW and using USRP-2920, a linear coding space-time architecture called V-BLAST ZF is created and the BER performance for 4 QAM and 16-QAM modulation is obtained.
In addition, the wireless system will obtain results from the constellation diagram, graphs of BER vs Eb / No and the transmission power to determine the quality of wireless communication, which will allow measuring the performance of the implemented system. |
