“…In a typical linear decentralized estimation setup, a large number of IoTNos are deployed in an area of interest which one wants to monitor. The IoTNos transmit their precoded observations over a coherent multiple access channel (MAC) to the FC for receiver combining (RC) and final estimation [16]. Coherent MAC requires that all the IoTNos in the network are synchronized and their individual transmitted signals arrive as a coherent sum at the FC.…”

“…The authors of [47] and [48] have proposed innovative robust LDE schemes based on majorization theory for non-sparse and sparse parameter estimation, respectively, where closed-form expressions for robust TPCs/ RC matrices were derived. Furthermore, the robust LDE of a temporally correlated parameter vector was considered in [49] under imperfect CSI considering both analog as well as quantized SN measurement transmission.…”

“…Hence, in a practical system, it is imperative to take the CSI uncertainty into account for achieving robust parameter tracking. To this end, similar to [49], [53], let the channel between each SN and the FC be modeled as…”

“…By alternatively minimizing the sequential MMSE, they designed near-optimal and linear compression strategies under power constraints. Following from [ 16 ], the authors continued to develop optimal pre-coders minimizing the sum-MSE for the scenario of transmitting quantized observations in [ 18 ].…”
