| Outline of Final Research Achievements |
This research project has further extended the result of our previous work: a narrowband signal processing method based on adaptive control of arbitrary variable digital filters. First, it has been theoretically proved that this method is of high quality and high reliability. Next, a unified framework has been established to minimize the degradation caused by the finite wordlength problem in implementation of this method. Furthermore, this method has been implemented on many practical applications of narrowband signal processing. Through performance evaluations of such applications, the utility of this method has been shown from the viewpoints of practical applications as well as mathematical theory.
