Intersymbol and Intercarrier Interference in OFDM Transmissions through Highly Dispersive Channels [PDF]
, 2019 This work quantifies, for the first time, intersymbol and intercarrier interferences induced by very dispersive channels in OFDM systems. The resulting achievable data rate for \wam{suboptimal} OFDM transmissions is derived based on the computation of ...

A Unifying Model for External Noise Sources and ISI in Diffusive Molecular Communication
, 2014 This paper considers the impact of external noise sources, including interfering transmitters, on a diffusive molecular communication system, where the impact is measured as the number of noise molecules expected to be observed at a passive receiver.

Gaussian Intersymbol Interference Channels With Mismatch [PDF]
IEEE Transactions on Information Theory, 2019 This paper considers the problem of channel coding over Gaussian intersymbol interference (ISI) channels with a given metric decoding rule. Specifically, it is assumed that the mismatched decoder has an incorrect assumption on the impulse response function. The mismatch capacity is the highest achievable rate for a given decoding rule.

Correlative coding with clipping and filtering technique in OFDM Systems [PDF]
, 2003 The major setbacks of Orthogonal Frequency Multiplexing (OFDM) is its peak-to-average power ratio (PAPR) and intercarrier interference (ICI). The occurrence of these factors restricts its application.

A Novel Optical Vector Spectral Analysis Technique Employing a Limited-Bandwidth Detector
EURASIP Journal on Advances in Signal Processing, 2005 A new technique for obtaining frequency-dependent magnitude and phase information across an optical channel is presented using tunable allpass optical filters and a detector with a small bandwidth relative to the full channel width.
