Notch filtering in power line communication

The power line communication (PLC), apart from the wireless one, is expected to become in the near future one of the most important technology of high-definition multimedia streaming in home environment. However, in order to realize this very optimistic scenario efficient combating synchronous and asynchronous impulsive disturbances, is necessary since they are especially harmful for assuring appropriate transmission bitrate and quality of service. In the paper potential application of notch filtering in the OFDM-based PLC environment is discussed and additionally compared to a novel modulation scheme proposed recently by the authors that makes use of circular real sine/cosine Gabor transform.
