摘要：
This paper investigates the influence of the different gains of weight branches to the dynamic characteristic and interference cancellation ratio (ICR) of an analog adaptive interference cancellation system (AAICS). We solved the transient-state and steady-state characteristics of weights. And the rule of ICR varying with the different gains was studied. The difference of the gains of weight control branches leads the convergence speeds of the two weights are different. The convergence speed of the system is decided by the slower weight. Enlarging the gains will improve the average convergence speed and ICR. The analyses are in agreement with the computer simulation. For the different gains, the system is a time-variant system. The more the difference of gains is, the severer THD (Total harmonic distortion) will be. And the new interference will appear.
