High SNR Linear Estimation of Vector Sources
IEEE Wireless Communications Letters, 2014 In this letter, we extend our prior work and consider decentralized estimation of unknown random vectors under high observation signal-to-noise ratio (SNR). A linear model is considered for decentralized estimation of vector sources. Observation models and sensor operations are both linear.
