摘要：
This paper briefly presents software defined radio (SDR) concept and layouts an overview of the actual state-of-the-art solution for power amplification systems and software enabled transmitters for SDR applications along with emerging related technology trends. Digital predistortion based linearization techniques, as an enabling technology for SDR transmitters, are briefly explained and discussed. Simulation results as well as experimental results are provided for LINC (linear amplification using nonlinear components) delta-sigma based transmitters to illustrate their respective performance and suitability for SDR applications.
