Abstract
In this paper, a novel adaptive energy and spectrum efficient inverse
power control method that is based on the truncated filtered-x LMS (FxLMS)
algorithm is introduced. By truncated power control we mean power control
where transmission is interrupted if the channel state deteriorates to bad
enough. Inverse power control minimizes the interference that a cognitive
radio (CR) creates to licensed users and allows more users to share the
spectrum. To further reduce the transmission power and consequently the
interference, truncation in power control is used. The performance of the
system is improved and the amount of needed transmitted energy is smaller.
Based on numerical analysis this new method offers energy efficient
transmission, helps to minimize interference to the primary users, and allows
even more users to share the same spectrum.
