Fading Channels: Information-Theoretic and Communication Aspects

IEEE Transactions on Information Theory, 1998
In this paper we review the most peculiar and interesting information-theoretic and communications features of fading channels. We first describe the statistical models of fading channels which are frequently used in the analysis and design of ...

Equivalent fading statistics in the K fading channels

2013 22nd Wireless and Optical Communication Conference, 2013
In order to obtain the fading statistics for the K fading channels, the equivalent process of the K process, i.e. the product process of a Rayleigh process and a Nakagami process, is utilized. The mapping relationship between the K process and its equivalent process is found by equating the arbitrary order moments of them. On this basis, the equivalent

The Fading Number of a Multiple-Access Rician Fading Channel

IEEE Transactions on Information Theory, 2009
The fading number of a noncoherent two-user Ri-cian fading channel is derived. The fading number is the second term in the high-SNR expansion of the sum-rate capacity of this multiple-access channel. It is shown that the fading number is identical to the fading number of the single-user Rician fading channel that is obtained when the user seeing the ...

A universal lattice code decoder for fading channels

IEEE Transactions on Information Theory, 1999
We present a maximum-likelihood decoding algorithm for an arbitrary lattice code when used over an independent fading channel with perfect channel state information at the receiver.

Fade margins for minimum duration outages in lognormal shadow fading and Rayleigh fading

Conference Record of the Thirty-First Asilomar Conference on Signals, Systems and Computers (Cat. No.97CB36136), 2002
Minimum duration outages have been used to characterize time-dependent performance in analysis of quantities such as average duration of an outage, the probability of outage, and the frequency of outage, in lognormal shadow fading (Mandayam et al., 1996) and Rayleigh fading (Lai and Mandayam, 1997), respectively.

Capacity of a Mobile Multiple-Antenna Communication Link in Rayleigh Flat Fading

IEEE Transactions on Information Theory, 1999
We analyze a mobile wireless link comprising M transmitter and N receiver antennas operating in a Rayleigh flat-fading environment. The propagation coefficients between pairs of transmitter and receiver antennas are statistically independent and unknown;

A simple and general parameterization quantifying performance in fading channels

IEEE Transactions on Communications, 2003
We quantify the performance of wireless transmissions over random fading channels at high signal-to-noise ratio (SNR). The performance criteria we consider are average probability of:error and outage probability.

On the Fade Duration Distribution in Nakagami Fading Channels

2007 IEEE International Conference on Communications, 2007
During almost fifty years the fade duration distribution (FDD) of random signals has been an open research topic. However, for Nakagami fading channels, and in general for the great majority of non-Gaussian processes, closed form general solutions are still unknown.

Fading and Diversity

2011
Fading is the variation in received signal strength due to changes in the physical characteristics of the propagation medium, which alter the interaction of multipath components of the transmitted signal. The principal means of counteracting fading are diversity methods, which are based on the exploitation of the latent redundancy in two or more ...
