Abstract
This paper is concerned with the signal to interference and noise ratio (SINR) estimation for wireless networks with SINR constraints and packet losses. A new SINR estimation method is proposed by using moving horizon estimation (MHE), where the SINR estimation system is described as a stochastic parameter system model. By choosing a stochastic cost function, the SINR estimator is obtained by solving a regularized least-squares problem. Considering the coupling of state variable and process noise, a one-step MHE algorithm is presented to solve the constrained SINR optimization problem by using LOQO algorithm. Finally, an illustrative example is given to demonstrate the effectiveness of the proposed method.
