Efficient BER simulation of orthogonal space-time block codes in Nakagami-m fading [PDF]
, 2014 In this contribution, we present a simple but efficient importance sampling technique to speed up Monte Carlo simulations for bit error rate estimation of orthogonal space-time block codes on spatially correlated Nakagami-m fading channels.

Normal approximations for fading channels [PDF]
2018 52nd Annual Conference on Information Sciences and Systems (CISS), 2018 Capacity and outage capacity characterize the maximum coding rate at which reliable communication is feasible when there are no constraints on the packet length. Evaluated for fading channels, they are important performance benchmarks for wireless communication systems. However, the latency of a communication system is proportional to the length of the

Capacity Results for Block-Stationary Gaussian Fading Channels with a Peak Power Constraint [PDF]
, 2006 We consider a peak-power-limited single-antenna block-stationary Gaussian fading channel where neither the transmitter nor the receiver knows the channel state information, but both know the channel statistics. This model subsumes most previously studied

On the Secrecy Capacity of Fading Channels [PDF]
2007 IEEE International Symposium on Information Theory, 2007 We consider the secure transmission of information over an ergodic fading channel in the presence of an eavesdropper. Our eavesdropper can be viewed as the wireless counterpart of Wyner's wiretapper. The secrecy capacity of such a system is characterized under the assumption of asymptotically long coherence intervals. We first consider the full Channel

Secret Sharing over Fast-Fading MIMO Wiretap Channels
EURASIP Journal on Wireless Communications and Networking, 2009 Secret sharing over the fast-fading MIMO wiretap channel is considered. A source and a destination try to share secret information over a fast-fading MIMO channel in the presence of an eavesdropper who also makes channel observations that are different ...

Degrees of Freedom of Generic Block-Fading MIMO Channels without A Priori Channel State Information
, 2014 We studynthe high-SNR capacity of generic MIMO Rayleigh block-fading channels in the noncoherent setting where neither transmitter nor receiver has a priori channel state information but both are aware of the channel statistics.

On Channel Estimation for OFDM/TDM Using MMSE-FDE in a Fast Fading Channel
EURASIP Journal on Wireless Communications and Networking, 2009 MMSE-FDE can improve the transmission performance of OFDM combined with time division multiplexing (OFDM/TDM), but knowledge of the channel state information and the noise variance is required to compute the MMSE weight.
