Development of Cost-Effective Wi-Fi 6 SISO/MIMO Vector Signal Generator and Analyzer

In order to reduce the R&D and testing costs of wireless communication products, this paper proposes a low-cost cross-platform Wi-Fi 6 SISO/MIMO vector signal generator and analyzer, by dismantling the traditional instrument architecture into core software, cross-platform control interface, and radio platforms. We develop the vector signal generation (VSG) software according to the specifications, and design the receiving end analysis algorithm to complete the development of the vector signal analysis (VSA) software. On the other hand, we also develop a cross-platform control interface, so that the core software can be integrated across platforms through this interface. The platforms we have completed integration include low-cost NI universal software radio peripheral (USRP) B/N/X series SDR platform and high-end NI vector signal transceiver (VST). Through this architecture, the radio platform can be flexibly selected according to the user's budget and needs, thereby greatly reducing the R&D and testing budget.
