Vector Spectrum Analyzer using USRP and Matlab applied to Wi-Fi Signals

The acquisition of sophisticated vector signal analyzer (VSA) may be a limiting factor for the execution of R&D projects due to prohibitive cost for some applications. In this work, conducted by three partners (UFAM/CETELI, ICTS and ENVISION/TPV), we propose a signal reception framework that use...

Description
Summary:The acquisition of sophisticated vector signal analyzer (VSA) may be a limiting factor for the execution of R&D projects due to prohibitive cost for some applications. In this work, conducted by three partners (UFAM/CETELI, ICTS and ENVISION/TPV), we propose a signal reception framework that uses the 802.11n standard to display measures of interest in order to analyze Wi-Fi signals cost-effectively. As result, four possible measurements were obtained: (i) transmission spectrum mask; (ii) spectral flatness; (iii) transmitter constellation error; (iv) transmitter modulation accuracy (EVM). The results indicates that this approach is a feasible VSA solution for R&D projects with budget limitations.
