Abstract: An OFDM encoding apparatus for encoding OFDM symbols into an OFDM signal includes: a pre-distortion unit that pre-distorts OFDM symbols into pre-distorted OFDM symbols, the OFDM symbols including payload data and each being carried on multiple OFDM subcarriers; an OFDM generator that generates an OFDM signal from the pre-distorted OFDM symbols by OFDM modulating the pre-distorted OFDM symbols; and a filter that filters the OFDM signal to obtain a filtered OFDM signal, the filter being configured to attenuate the spectrum of the OFDM signal in frequency bands outside the signal bandwidth of the OFDM signal by applying a filter transfer function to the OFDM signal. The pre-distortion unit is configured to apply a pre-distortion transfer function equal to the inverse of the filter transfer function to the OFDM symbols.

Abstract: A method for transmitting a signal from a transmitter over a channel to a receiver on a Power Line Network, wherein said signal is OFDM-modulated on a set of sub-carriers, is proposed, wherein an OFDM tonemap and an eigenbeamforming encoding matrix are determined based on a channel estimation for each sub-carrier, a tonemap feedback signal and an eigenbeamforming feedback signal are generated, which are descriptive of said OFDM tonemap and said eigenbeamforming encoding matrix, respectively, and transmitted to the transmitter. A corresponding receiver, a transmitter, a power line communication and a power line communication system are described as well.
