| Abstract(in English) | In this paper, we discuss precoder optimization in wireless data aggregation. Formulate the problem of minimizing the mean square error between the estimated signal and the source signal in a data aggregator under power and block diagonal constraints, We solve the optimization problem using the projective gradient method with projection onto the constraint set. By using the information of the source signal in the objective function, the optimization can be performed taking into account the correlation among the data. Through numerical experiments, we confirm the performance of the optimized precoder. |
