Adaptive multidimensional coded modulation over flat fading channels
TL;DR: A general adaptive coding scheme for Nakagami multipath fading channels using a set of 2L-dimensional (2L-D) trellis codes originally designed for additive white Gaussian noise channels is introduced.
Journal ArticleDOI
Impact of channel prediction on adaptive coded modulation performance in Rayleigh fading
TL;DR: This paper investigates the effects of predicting the CSI using a linear fading-envelope predictor in order to enhance the performance of an ACM system and obtains approximative closed-form expressions for BER and average spectral efficiency.
Journal ArticleDOI
Sum and difference of two squared correlated Nakagami variates in connection with the McKay distribution
Henrik Holm,Mohamed-Slim Alouini +1 more
TL;DR: General formulas for the probability density function of the sum and the difference of two correlated, not necessarily identically distributed, squared Nakagami variates (or equivalently, gamma variates) are derived and are shown to be in the form of the McKay "Bessel function" distributions.
Proceedings ArticleDOI
Optimal power control for discrete-rate link adaptation schemes with capacity-approaching coding
TL;DR: This work proposes a variable-power transmission scheme for slowly varying flat-fading channels using a fixed number of codes, and shows that the power adapted transmission scheme achieves a spectral efficiency within 0.15 bits/s/Hz of the Shannon capacity for continuous rate and power adaptation.

Method and apparatus for wireless asset tracking using asset tags with motion sensors
Henrik Holm,Steve D. Huseth +1 more
TL;DR: In this article, the authors propose a system that includes an asset tag associated with an asset, the asset tag having a motion sensor to detect a movement of the asset and a plurality of readers, each reader receiving one or more signals from the tag and measuring a distance between tag and reader based on the signals.
