摘要: A dynamic scaling scheme is developed to resolve the overflow problem in fixed-point system which optimized by simulation-based range estimation method. When a signal larger than expected value, dynamically changes factor of input and internal variables remove overflow. Finally, recovers scale factors after given period time. An adaptive noise canceller was implemented with proposed
