Fig. 4From: Successive interference cancellation aided sphere decoder for multi-input multi-output systemsBER performance with LS channel estimation. Comparison with imperfect channel estimates between the proposed and other CSDs for N t =N r =8 with 8PSK. Note that the curves of the conventional SE-CSD, Pham-CSD, PTP-CSD, and proposed-CSD w/ AC are superimposedBack to article page
