Power Control for Broadcast V2V Communications with Adjacent Carrier Interference Effects
Paper in proceedings, 2016
This paper investigates the power control problem
for broadcast vehicular communications in the presence of
adjacent channel interference (ACI). First, we study the impact
of ACI on vehicle-to-vehicle (V2V) communications and conclude
that the ACI indeed significantly affects the reliability of V2V
links. Second, we formulate a power control optimization problem
for vehicles to reduce the negative influence of ACI, which is
shown to be NP-hard. Furthermore, we propose two power
control schemes where the first one solves the formulated problem
by a branch and bound method and the second one considers
a heuristic algorithm with much reduced complexity. Finally,
simulations are presented which illustrate the necessity of power
control when ACI exists and also show promising performance
of the proposed algorithms.
