On the genetic optimization of APSK constellations for satellite broadcasting
Both satellite transmissions and DVB applications over satellite present
peculiar characteristics that could be taken into consideration in order to
further exploit the optimality of the transmission. In this paper, starting
from the state-of-the-art, the optimization of the APSK constellation through
asymmetric symbols arrangement is investigated for its use in satellite
communications. In particular, the optimization problem is tackled by means of
Genetic Algorithms that have already been demonstrated to work nicely with
complex non-linear optimization problems like the one presented hereinafter.
This work aims at studying the various parameters involved in the optimization
routine in order to establish those that best fit this case, thus further
enhancing the constellation.Comment: IEEE International Symposium on Broadband Multimedia Systems and
