innovating communications - CTTC

Moreover, during 2007, CTTC has submitted to OEPM
(Oficina Española de Patentes y Marcas) and to EPO three
additional PCT patents related to other research and
development activities carried out in the center.
The first one, promoted by the inventors M. Portolés, A.
Krendzel, J. Mangues, defines a method to characterize
the capacity of a wireless node and to detect the activity
of other nearby wireless nodes when implementing a
distributed access communication protocol.
The second patent, authored by N. Zorba, A. Perez describes
a method for allocating a minimum downlink power
from a transmitter of a cellular multi-user multi-antenna
communications system. This amount of power depends
on the channel interference and on a predetermined
quality of service requirement per user.
Finally, the third patent, promoted by the inventors N. Zorba,
M Realp, A. Perez, is a signal processing scheme for wide
band communications systems using satellite channels.
This scheme takes advantage of the information of the
antenna radiation diagram. By using this information, the
signal is processed before its transmission, improving the
performance of the system.
