Fusion Performance in Wireless DS-CDMA Sensor Networks with Analog Relay Local Processing Scheme
The performance of decentralized detection in power constrained wireless sensor network is analyzed. By using the distributed processing schemes with the analog relay amplifier local processing, this system is proposed to be subjected to a total power constrains. And, the distributed nodes are assumed to perform analog relay amplifier local processing. Under such conditions the effect of the sensor to fusion communication by making use of the DS-CDMA concept. It evolves the fusion performance by using non-orthogonal sensor-to-fusion center communication, as opposed to the orthogonal communication. Also, to quantify the performance a circulant matrix theory is used to derive closed form asymptotic expressions. The presented results show the effect of each parameter on the total system performance.
