An Algorithm for Positioning Relays and Point Scatterers in Wireless Systems
Journal article, 2008
In this letter, we discuss the problem of positioning
an unknown number of amplify-and-forward relays or point scatterers
using a wireless network of wideband transceivers.We propose
to model this positioning problem as an assignment problem.
In doing so, we avoid the problems associated with an exhaustive
gridsearch approach, which has recently been proposed to solve the
problem. Numerical simulations showpromising results in terms of
performance and robustness.
