Abstract:
|
A novel technique to obtain optimum blind spatial
processing for frequency diversity spread spectrum (FDSS) communication
systems is introduced. The sufficient statistics for a
linear combiner, which prove ineffective due to the interferers frequency
characteristics, are modified to yield improved detection
under partial jamming in the spectral domain. Robustness to partial
time jamming is achieved by extending the notion of replicas
over the frequency axis to a repetition over the time variable. Analysis
and simulations are provided, showing the advantages of using
FDSS with spatial diversity to combat the interference when it is
confined to a narrow frequency band or short time interval relative
to the desired signal extent in either domain. |
