| Summary: | In the wireless mobile communications the
knowledge of the mobile speed and/or the mobile velocity is
of great importance because it is very helpful in the
development of the system management algorithms (i.e. the
handoff algorithms). Furthermore, the angle of mobile
motion is more helpful for developing these algorithms and
also in the mobile unit (MU) tracking systems. The proposed
scheme showed that in distributed antenna system (DAS),
the speed of MU at any point can be estimated using Doppler
frequency estimation. The angle at which MU is traveling
with respect to angle zero is derived in terms of Doppler
frequency at two nearby locations. A numerical examples
and comparison with test angles results were shown the
accuracy of the estimation scheme within the real systems
range of values. |
