Powerline Communication: Efficient Communication Considerations

This paper focuses on the efficiency considerations while implementing Powerline Communication. The OFDM modulation scheme is deliberated, before introducing the adaptation of Hadamard Coded Modulation. The BER and Peak-to-average ratio (PAPR ) of OFDM are discussed in conjuncture with those of Hadamard Coded Modulation. Further discussions are made on reducing DC Bias without significant Information Loss and concept of interleaving for dispersive channels. Security of system is also preconceived
