Sethuraman, Vignesh, Wang, Ligong, Hajek, Bruce, Lapidoth, Amos
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 or the...
Low SNR Capacity of Fading Channels -- MIMO and Delay Spread (2007)
Sethuraman, Vignesh, Wang, Ligong, Hajek, Bruce, Lapidoth, Amos
Discrete-time Rayleigh fading multiple-input multiple-output (MIMO) channels are considered, with no channel state information at the transmitter and receiver. The fading is assumed to be correlated...
Low SNR Capacity of Fading Channels with Peak and Average Power Constraints (2006)
Sethuraman, Vignesh, Hajek, Bruce
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 time is derived. A low...
On communication over correlated fading channels with practical power constraints / (2006)
A discrete-time single-user scalar channel with temporally correlated Rayleigh fading is analyzed. There is no side information at the transmitter or the receiver. A simple expression is given for...

Comments on `Bit Interleaved Coded Modulation' (2005)
Sethuraman, Vignesh, Hajek, Bruce
Caire, Taricco and Biglieri presented a detailed analysis of bit interleaved coded modulation, a simple and popular technique used to improve system performance, especially in the context of fading...
Capacity per Unit Energy of Fading Channels with a Peak Constraint (2005)
Sethuraman, Vignesh, Hajek, Bruce
A discrete-time single-user scalar channel with temporally correlated Rayleigh fading is analyzed. There is no side information at the transmitter or the receiver. A simple expression is given for...
Capacity per unit energy of fading channels with a peak constraint (2005)
Vignesh Sethuraman, Bruce Hajek
A discrete-time single-user channel with correlated Rayleigh fading is analyzed. At low SNR, the capacity of such a channel is known to be achieved by input signals with large peak powers. Since such...
Capacity per unit energy of fading channels with a peak constraint (2005)
Vignesh Sethuraman, Bruce Hajek
Abstract — We consider a discrete-time flat fading channel with no side information. We bound the capacity of such a channel by finding the capacity per unit energy in the presence of a hard peak...
