100(Z@F6 52 13 @ 0 CIO 6 PILOT AND DATA TRANSNUSSION IN A QUASI-ORTHOGONAL SINGLE-CARRIER FREQUENCY DIVISION MULTIPLE ACCESS SYSTEM ABSTRACT 5 1001341 IN A SINGLE-CARRIER FREQUENCY DIVISION MULTIPLE ACCESS (SC-FDMA) SYSTERN THAT URILIZES INTERLEAVED FDMA (UDNIA) OR LOCALIZAL FL)MA, RMILTIPIC TRANSMITTERS MAY TRANSMIT THEIR PILOTS USING TIME DIVISION MULTIPLEXING (TDM), CODE DIVISION MULTIPLEXING (CDW, INTERLEAVED FREQUENCY DIVISION MULTIPLEXING (IFDM), OR LOCALIZED FREQUENCY DIVISION MULTIPLEXING (LFDM). THE PILOTS FROM THESE TRANSMITICIS ARE THEN 10 ORTHOGONAL IO ONE ANOTHER. A RECEIVER PERFORMS THE.COMPLEMCNIARY DEMULTIPLEXING FOR THE PILOTS SENT BY THE TRANSMITTERS. THE RECEIVER MAY DERIVE A CHANNEL ESTIMATE FOR EACH TRANSMITTER USING AN MMSF TECHNIQUE OR A LEAST-SQUARES TECHNIQUE. THE RECEIVER MAY RECEIVE OVERLAPPING DATE TRANSMISSIONS SENT ON THE SAME TINTE-FRNUENCY BLOCK BY THE MULTIPLE TRANSTNIIIERS AND MAY PERFORM RECEIVER SPATIAL PROCESSING WITH SPATIAL FILTER 15 MATRICES LO SEPARATE THESE DATA TRANSMISSIONS. THE RECEIVER MAY DERIVE DIE SPATIAL FFLTER MATRICES BASED ON THE CHANNEL ESTIMATES FOR THE TY',MSTNITTERS AND USING ZERO-FORCING, MNISE, OR MAXIMAL RATIO COMBINING TCCHN@IQUE.
