ErrorCharacteristics ofFMFamily Codes Using PRML

hi thispaper, we clarify the properties ofthirty FM family codesthrough analyses oftheir coding rules. We theninves¬ tigate combinations ofthese codes with sever¬ alPRML techniques bysimulating biterror rates. Theresults showthatnineFM family codesyield a better SNRthandoesthecon¬ ventional FM codeatthebit errorrateofIO*4.
