Abstract:
|
This paper addresses the problem of transmit beamforming
in open spectrum communication systems. In these
scenarios, the operator or the data communication provider
delivers a set of base stations to the final users under no radio
planning strategy. In order to deal with such an uncoordinated
communication system, this work presents a centralized algorithm
for calculating the optimal precoding strategy the via
semidefinite relaxation technique. The problem to be solved
is a novel design of minimum norm beamformers under QoS
and received power constraints. Numerical results will show the
performance of the method. |
