This is a discussion document for the IEEE document of the IEEE 802.15. 4a channel
modeling subgroup. It provides models for the following frequency ranges and …

Relayed transmission is a way to attain broader coverage by splitting the communication link
from the source to the destination into several shorter links/hops. One of the main …

Capitalizing on the Moschopoulos (1985) single gamma series representation of the
probability density function (PDF) of the sum of gamma variates, we provide a PDF-based …

This book introduces the theoretical elements at the basis of various classes of algorithms
commonly employed in the physical layer (and, in part, in MAC layer) of wireless …

Moment-based estimation of the Nakagami-m fading parameter is studied. A family of new,
generalized, estimators, based on real (integer and possibly noninteger) sample moments …

Multi-user cooperative diversity is a recent technique promising great improvement of the
performance of wireless communication systems operating in fading environments. Based …

Orthogonal frequency division multiple access (OFDMA) systems, such as IEEE 802.16 e/m
and 3GPP Long Term Evolution (LTE), require significantly large signaling overhead for …

The problem of estimating the K parameter and the local average signal-to-noise ratio in a
noisy Ricean fading channel is studied. Unlike most previous estimators where independent …

We present the site-specific signal strength measurement results for path loss, shadowing,
and fading in 2.4 GHz band under typical harsh environment (high temperature 40-50 C and …

The generalized method of moments (GMM) is introduced in the framework of estimating the
Nakagami-m fading parameter. This GMM approach provides a systematic procedure for …
