Portable Spectrum Analyzer Application using Android based on Software Defined Radio (RTL-SDR)

摘要

In this research, it is proposed to develop spectrum analyzer using RTL-SDR based on SDR Console 2. This device was then integrated with Android to do the real value calculation. The measurement results were then validated and regression was performed. The result of analysis shows that regression with linear approach has error of 4.84% second order error of 4.83%, third order error of 4.84% and fourth order error of 7.31%. Based on regression, the first order is chosen because the error value was still below 5% with the simplest equation.
