On the capacity and normalisation of ISI channels [PDF]
IEEE International Conference on Communications, 2003. ICC '03., 2003 We investigate the capacity of various intersymbol interference (ISI) channels with additive white Gaussian noise (AWGN). Previous papers showed a minimum E/sub b//N/sub 0/ of -4.6 dB, 3 dB below the capacity of a flat channel, is obtained using water-pouring capacity formulas for the 1+D channel.

Analysis of Massive MIMO Performance in an Indoor Picocell With High Number of Users
IEEE Access, 2020 This paper presents an analysis of the massive multiple input and multiple output (MIMO) channel in an indoor picocell with a high number of active user terminals and a base station consisting of a virtual array with up to one hundred elements.

Convexity of the Capacity of One-Bit Quantized Additive White Gaussian Noise Channels
Mathematics, 2022 In this study, the maximum error-free transmission rate of an additive white Gaussian noise channel with a symmetric analog-to-digital converter (ADC) was derived as a composite function of the binary entropy function, Gaussian Q-function, and the square

On the capacity of the noncausal relay channel [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 This paper studies the noncausal relay channel, also known as the relay channel with unlimited lookahead, introduced by El Gamal, Hassanpour, and Mammen. Unlike the standard relay channel model, where the relay encodes its signal based on the previous received output symbols, the relay in the noncausal relay channel encodes its signal as a function of ...

On the MIMO Channel Capacity for the Nakagami-$m$ Channel [PDF]
IEEE Transactions on Information Theory, 2007 This paper presents the MIMO channel capacity over the Nakagami-m fading channel. The joint eigenvalue density function of W = HHdagger, where H is the channel matrix, is derived in a closed form in the 2 times 2 case and for integer values of m, as well as for m rarr infin.

On the capacity of MIMO interference channels [PDF]
2008 46th Annual Allerton Conference on Communication, Control, and Computing, 2008 The capacity region of a multiple-input-multiple-output interference channel (MIMO IC) where the channel matrices are square and invertible is studied. The capacity region for strong interference is established where the definition of strong interference parallels that of scalar channels.

Determining Causal Skeletons with Information Theory
Entropy, 2020 Modeling a causal association as arising from a communication process between cause and effect, simplifies the discovery of causal skeletons. The communication channels enabling these communication processes, are fully characterized by stochastic tensors,
