Abstract :
We consider the uplink of a multi-cell multiuser multiple-input multiple-output time-division duplexing (TDD) system. The data detection is done by using MMSE filer taking pilot contamination into consideration. Employing the equivalent channel model of MMSE channel estimation, we find an interesting characteristic of user´s SINR. In view of the characteristic, we derive new, exact closed-form expressions for the uplink symbol error rate for M-PSK in i.i.d Rayleigh fading channels. Numerical results are presented to verify our analysis.
