PROJECT TITLE :

Impact of RF–Switch Insertion Loss on the Performance of Space Modulation Techniques - 2018

ABSTRACT:

The RF switch has been highlighted recently as a core element for hardware implementations of the transmitters of space modulation techniques (SMTs). As several alternative RF elements, RF switches have imperfections which will negatively have an effect on the bit error performance of the system. Out of the various imperfections, insertion loss, in particular, is an RF switch property that reflects negatively on the performance of SMTs. Insertion loss in an RF switch causes mismatch between the transmitter and receiver constellation diagrams thanks to power loss in the transmitted signal. During this letter, the impact of insertion loss is studied analytically and substantiated through Monte Carlo simulation results. It's revealed that insertion loss can considerably impact the system performance if not addressed properly.
