We consider distributed estimation of a random vector signal in a power
constraint wireless sensor network (WSN) that follows multiple-input and
multiple-output (MIMO) coherent multiple access channel model. We design linear
coding matrices based on linear minimum mean squared error (LMMSE) fusion rule
that accommodates spatial correlated data. We also derive a lower bound to this model.
Simulation results show that when the data is more correlated, the
distortion in terms of mean squared error (MSE) degrades. By taking into account the
effects of correlation, observation, and channel matrices, the proposed method
performs better than equal power method. |
