| Research Abstract |
Sensor collaborative beam forming in which plural transmit sensors collaborate to form a signal beam is proposed to realize highly reliable signal transmission in wireless sensor network systems. The evaluation results confirm that the proposed beam forming method can effectively decrease total power consumption and perform highly-accurate estimation of offset frequency under inter-symbol and co-channel interference conditions.
