Abstract :
This paper discusses an adaptive structure which enables the detection and enhancement of narrow-band signals which have been corrupted by broad-band noise. A parallel configuration of second-order IIR adaptive filters is utilized, thus allowing detection of multiple signals. A gradient search algorithm is derived and the corresponding performance surface is evaluated.
