To the equalizer problem in FIR-MIMO(finite impulse response-multiple-input multiple-output)channels with common zeros under binary inputs,the existence condition of FIR-SIMO channel with common zeros is extended to that of FIR-MIMO channels.We investigate the equalizer problem of a FIR-MIMO system with common zeros.One sufficient condition for the existence of an equalizer for the system with binary inputs and the specific form of the corresponding equalizer is obtained under certain conditions.The experimental result on the feasiblity of the condition shows that no matter the common zeros of the channels lie within the internal or external of the unit circle,the equalizers can always be found as long as the sufficient condition is satisfied.
