How many known symbols are required for linear channel estimation in OFDM?
Training sequences for estimation of channel parameters have been well designed under the condition that the number of the unknown channel parameters is not greater than the numbe...

On The Optimal Amount of Training for Peak-Power-Limited Rayleigh Fading Channels
— We consider the optimal amount of training for single-antenna Rayleigh flat fading channels with peak-powerlimited input. The receiver uses known training symbols to perform m...

On models for multi-user Gaussian channels with fading
Abstract— An analytically tractable model for Gaussian multiuser channels with fading is studied, and the capacity region of this model is found to be a good approximation of the...

Delay-rate tradeoff for ergodic interference alignment in the Gaussian case
In interference alignment, users sharing a wireless channel are each able to achieve data rates of up to half of the non-interfering channel capacity, no matter the number of users...

Effect of Feedback Delay on Multi-Antenna Limited Feedback for Temporally-Correlated Channels
— A novel method based on Markov chain theory is proposed for analyzing the effect of feedback delay on a transmit beamforming system with limited feedback. Using this method, th...
