1、The proposed a new method for signal recovery in multiuser multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) system with knownpartial channel state information.The dispersive channel
2、in multiuser MIMO_OFDM systemcan be seen as set ofinstantaneous mixtures for the perspective of frequency bin (FB),Whena new user arrives,the new interferences are introduced making an expanding mixture.Thechannel state
3、information (CSI) is estimated with pilot symbols,recovering the transmittedsignals.However,if the new user's CSI is known,it can be used to recover the transmittedsignals,instead of the bandwidth waste pilot symbols.In
4、the proposed method,from thesecond order statistics of the received signals,the parameters of the mixture caused by newuser are extracted.Then the signals belong to different users are separated at each FB,wherethe new j
