Abstract
Conventional adaptive filters only suit stationary and slowly time-varying nonstationary inputs. Based on the previous work on linear almost periodically time-varying adaptive filtering, the authors develop such an adaptive filter adopting the output-modulator structure. In addition to being capable of dealing with almost cyclostationary inputs (an important class of nonstationary signals), this scheme is also able, by means of adaptive frequency tracking, to remain synchronous with the varying input statistics.<>
