Notes from IEEE Smart Grid Short Course - Tutorial paper - Video demos of impulsive noise
Smart meter communication over power lines is attractive because it uses existing infrastructure. However, it is limited by the strong impulsive noise, esp. from power electronics and wireless signals, within the 3-500 kHz transmission band.
In improving reliability of smart meter powerline communication (PLC), we derive impulsive noise models using field measurements, develop receiver methods to mitigate the noise, and implement those methods in our real-time testbed. One of our impulsive noise models has been adopted by the IEEE 1901.2 PLC standard. Our receiver methods demonstrate up to 10 dB of SNR gain, or equivalently up to a 4x increase in bit rate for the same bit error rate.
