“…While above this threshold, LDPC codes perform well in AWGN, but below it, the codes provide no error correction capability. In [35], it is shown that cyclostationary noise can have a dramatic effect on the performance of LDPC codes at much smaller interference powers than what has been simulated in this paper. is defined according to the sampling rate.…”

This paper presents a novel method for enabling communication in cyclostationary interference limited environments by adaptively inserting and exploiting spectral redundancy in an orthogonal frequency division multiplexing (OFDM) signal. The redundancy is formed through repeating data symbols across OFDM symbols in both time and frequency. A novel frequency shift (FRESH) filter is applied to exploit the time-varying cyclostationary properties, enabling the communication while under interference. The ability to design an interference mitigating property into the communication signal creates a new degree of freedom when optimizing and adapting a waveform's parameters. Simulation results demonstrate the performance gains in both signal to interference and noise ratio (SINR) and bit error rate (BER) as compared to traditional time-invariant optimal filtering techniques and error correcting codes (ECC).

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 highdefinition 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.

“…In the Power Line Communications (PLC) environment [1], Low-density parity-check (LDPC) codes [2], [3] have been considered as channel coding solution [4], [5], especially for their capability to limit the influence of the power line noise [6], [7]. In particular, LDPC coded modulations, tailored to the improvement of the spectral efficiency of the digital transmission systems, are of interest.…”

We discuss the performance of different coding schemes based on the use of short LDPC codes, which are suitable for the application in Power Line Communications (PLC) systems, where low latency and high spectral efficiency is requested. We identify the class of LDPC codes appropriate for this purpose in the codes used in IEEE 802.16e standard (WiMAX). We then propose different coding schemes and conduct a performance analysis in terms of their capability of achieving the capacity in an Additive White Gaussian Noise (AWGN) channel, while keeping low the overall latency of the encoding/decoding process. We also consider the presence of bursty impulse noise, in order to investigate a typical PLC scenario. The analysis proves that WiMAX standard LDPC codes, used with proper coding schemes, achieve competitive trade-off between spectral and energy efficiency, maintaining the compatibility with the considered latency constraint.
