The problem of jonit delay-filter identification is concerned with conventional time-delay es-timation, modeling of adaptive spstem and time-delay estimation This paper deals with system model of first filterthen time-delay, improved the algorithm of recursive least squares filter baased on fast across filter form Boudrfau& Kabel, the time complexity is redused from 0[19ρ] to 0[7ρ].
时滞和滤波联合辨识问题既是经典时滞估计问题的推广，又是自适应系统建模和时灌估计两方面的交叉。
