26 OATA DETECTION AND DFCODING "ITH CONSIDERATION'S F(R CHAMO',L ESTINIATION ERRORS DUE TO GUARD SUBBANDS ABSTFZACT 5 TECHNIQUCS FOR PERFORURIN.G DATA C1CIECIJON.9ND DECOD@NOQ IN A MANNER TO ACCOUNT FOR GUQTD SUBBANDS ARE, DESCRIBED. A RECEIVER OBTAINS RECEIVED PILOT SYMBOLS FOR PILOT SUBBANDS AND RECEIVED DATA SYMBOLS FOR DATA SUBBANCLS. CHANNEL ESTIMATES ARE DERIVED BASED ON THE RECEIVED PILOT SY'MBOLS WITH ZCIOCD-OUT PILOT SUBBANDS FILLED WITH ZEROS. DATA DETECTION IS PERFORMED ON THE RECEIVED CLAT A SYMBOLS WITH THE CHANNEL ESTIMATES TO 10 OBRAM DATA SYMBOL ESTIMATES. FSFIRN@IES OF NOISE AND ESTIMATION ERRORS DUE TO THE ZEROED-OAT PILOT SUBBANDS ARE DERIVED. LLRS ARE THEN COMPUTED BASED ON THE DATA SYMBOL ESTIMATZS, THE CHANNEL ESTIMATES, AND THE ESTIMATES OF THE TIOISC AND ESTIMATION ERROIS. THE LLIZS ARE DEINTERLEAVED AND DECODED TO OBTNM DECODED D;IIA.
