| Outline of Final Research Achievements |
This research studies adaptive transmission and frequency offset estimation for sensor collaborative beam forming. In addition, power consumption reduction effect with the beam forming is evaluated by computer simulation.
A sensor collaborative beam forming method with adaptive transmission is proposed in which collaborative sensor selection and beam forming are performed according to obtained reception quality in a receiving sensor. The simulation result with the proposed method shows that total power consumption of the beam forming with 5 collaborative sensors can be reduced by 60%. The result also shows that offset frequency among transmitting and collaborative sensors can be estimated at practical accuracy even under co-channel interference.
