Sensor placement minimizing the state estimation mean square error: Performance guarantees of greedy solutions [PDF]
2020 59th IEEE Conference on Decision and Control (CDC), 2020 This paper studies selecting a subset of the system's output to minimize the state estimation mean square error (MSE). This results in the maximization problem of a set function defined on possible sensor selections subject to a cardinality constraint. We consider to solve it approximately by a greedy search.

Robust precoder design in MISO downlink based on quadratic channel estimation [PDF]
, 2008 In [1], it has been proposed that channel estimates in quadratic form can be obtained at the base station by sending training sequences to the mobiles where the received signals are forwarded back to the base for channel estimation.
