WebFirst, we formulate the problem of distributed esti- mation fusion in a general setting of best linear unbiased estimation (BLUE), also known as linear unbiased least mean-square (LMS) estimation. For unbiased local esti- mators, the linear, unbiased fused estimator of the small- est mean-square error is their weighted sum with a matrix weight.
