Identification of impulsive interference channels
… parameters of the Middleton Class A impulsive interference model is considered. In particular, under the assumption of the availability of a set of independent samples from the Class A envelope distribution, the problems of basic batch estimation of the Class A parameters, recursive …

Interference channels with coordinated multi-point transmission
… tractable way to characterize the capacity of interference channels. The considered channel model has K transmitter/receiver pairs, and each receiver is interested in one unique message from a set of K independent messages. Each message can be available at more than one transmitter. The maximum …

Interference channels with half-duplex source cooperation
… source cooperation is studied for Gaussian interference channels. The source cooperation is in-band, meaning that each source can listen to the other source's transmission, but there is no independent channel between the sources; half-duplex assumes that, at each time instant, the sources …

An information theoretic study of reduced-complexity receivers for intersymbol interference channels
… a discrete-time additive Gaussian intersymbol interference channel typically grows exponentially with the duration of the channel impulse response. Consequently, practical sub-optimal receivers are often designed as though the channel impulse response were shorter than it is. While previous …

A class of batch-iterative methods for the equalization of intersymbol interference channels
… receivers is proposed to equalize intersymbol interference (ISi) channels in a batch-iterative fashion. The iterated-decision or multipass equalizer uses symbol decisions made during the previous iteration to cancel out both precursor and postcursor ISi during the current iteration. With each …
