抄録

A novel method for signal recovery in multiuser multi-input multi-output(MIMO) orthogonal frequency division multiplex(OFDM) systems with known partial channel state information(CSI) is proposed. Upon the arrival of a new user, the new interferences are introduced which results an expanding mixture. Usually, with the help of pilot symbols, the CSI is estimated. In this letter, from the second order statistics of the received signals, the parameters of the mixture caused by the new user are extracted. Then the signals from different users are separated at each frequency bin (FB).
