This　paper　presents　a　multiple　feedback　interference　cancellation　scheme　based　on　the　Partitioned　Block　Frequency-Domain　LMS　algorithm　for　a　CMMB　(China　Mobile　Multimedia　Broadcasting)　radio　repeater　when　the　isolation　between　the　transmitting　and　receiving　antennas　is　much　larger　than　the　gain　of　the　radio　repeater　to　provide　a　larger　coverage　range.　If　the　large　feedback　signals　received　at　the　receiving　antenna　can＇t　be　suppressed　by　the　repeater,　the　repeater　will　get　into　a　vicious　circle　of　sustained　enlargement　until　it　goes　into　self-oscillation.　The　performance　evaluation　of　the　designed　scheme　is　illustrated　with　simulation　results.　©　2012　IEEE.
