Energy-Efficient Signal Processing Techniques for Smart Grid Heterogeneous Communication Networks
Powerline communications (PLC) and unlicensed wireless communications are two leading communications technologies for emerging Smart Grid applications. The channel and noise statistics experienced by PLC and wireless transmissions are independent resulting in media diversity. In this project, we exploit this new form of diversity by transmitting the same information signal over the powerline and wireless links and combining the two received signals to enhance communication reliability.
In this talk, I will compare the performance of three receive-signal diversity-combining techniques for coherent and differential two-way communication between smart meters and data concentrators over low-voltage powerlines. In addition, I will show how to apply multi-input multi-output (MIMO) communications principles to enhance the data rates of PLC signals as they travel through the low-voltage to medium-voltage transformer and over several kilometers of medium-voltage powerlines.
