Smart Grid Communications Project
Two-way communication is a key feature in a smart grid.
It is enabled by either powerline communication or wireless communication
Utilizing both technologies can potentially enhance communication reliability,
and many diversity combining schemes have been proposed.
In this paper, we propose a flexible real-time testbed to evaluate diversity
combining schemes over physical channels.
The testbed provides essential parts of physical layers on which both
powerline and wireless communications operate.
The contributions of this paper are
Bit error rate curves obtained from simulations and measurements over physical
channels show that performance of MRC in practice is comparable with simulation
in various test cases.
- implementation of a real-time testbed for diversity of simultaneous
powerline and wireless communications, and
- performance evaluation of maximal ratio combining (MRC) on the testbed.
