MMSE Receiver for Multiuser Interference Cancellation in Uplink OFDMA
, 2006 In uplink orthogonal frequency division multiple access (OFDMA) systems, multiuser interference (MUI) occurs due to different carrier frequency offsets (CFO) of different users at the receiver. In this paper, we present a minimum mean square error (MMSE)
