Reduced-complexity bandwidth-constrained distributed estimation for wireless sensor networks
Trent Jacobs, Hlaing Minn, Naofal Al‐Dhahir · 2007
While elegant in form, the maximum likelihood estimator (MLE) for heavily bandwidth-constrained distributed estimation in Gaussian noise is computationally expensive to implement. We consider an alternative estimator for this case which requires far less computational complexity, yet performs close to the MLE under the same operating conditions.
