Channel capacity in the limit of vanishing signal-to-noise ratio (SNR) per degree of freedom
is known to be linear in SNR for fading and nonfading channels, regardless of channel state …

We derive bounds on the noncoherent capacity of wide-sense stationary uncorrelated
scattering (WSSUS) channels that are selective both in time and frequency, and are …

In this paper, the capacity and energy efficiency of training-based communication schemes
employed for transmission over a priori unknown Rayleigh block-fading channels are …

Transmission of information over a discrete-time memoryless Rician fading channel is
considered, where neither the receiver nor the transmitter knows the fading coefficients. The …

Discrete-time Rayleigh-fading single-input single-output (SISO) and multiple-input multiple-
output (MIMO) channels are considered, with no channel state information at the transmitter …

This paper considers an additive noise channel where the time-A; noise variance is a
weighted sum of the squared magnitudes of the previous channel inputs plus a constant …

This paper investigates the signal‐to‐interference ratio and the achievable rates of
underwater acoustic (UA) OFDM systems over channels where time and frequency …

Millimeter wave (mmWave) communications use large transmission bandwidth and
experience severe propagation conditions. This forces the communication system to operate …

We derive a lower bound on the capacity of discrete-time Rician-fading channels that are
selective both in time and frequency. The noncoherent setting is considered, where neither …

Flat-fading channels that are correlated in time are considered under peak and average
power constraints. For discrete-time channels, a new upper bound on the capacity per unit …
