| Research Abstract |
Firstly, this study improved the operating time of sensor nodes by reducing the communication cost and also improved the coverage time of the whole observation area. Secondary, as a contribution to the power saving of transmitter amplifier, this study proposed GA based peak power reduction methods for OFDM signal. Further, as effective information integration techniques, this study proposed vector quantization algorithms based on ensemble learning that have good generalization ability and good time efficiency.
