摘　　要：针对两字符输入下含公零点的FIR-MIMO(finite impulse response-multiple-input multiple-output)信道的均衡器问题,把含公零点的FIR-SIMO信道均衡器存在性条件推广到了FIR-MIMO信道上。在一定条件下,给出了两字符集输入下信道均衡器存在的一个充分条件及此条件下相应均衡器的具体形式。关于充分条件可行性的实验结果表明,在含公零点的信道中,无论公零点在单位圆内或者圆外,只要满足所给的充分条件,都能够找到正确恢复信号的均衡器。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.
