Adaptive noise cancelling of a sinusoidal interference using a lattice structure

Lattice structures have recently been proposed for application to such areas as adaptive linear prediction, adaptive noise cancelling, and adaptive equalization. In this paper, we will consider the suppression of a sinusoidal interference by the use of an adaptive lattice structure implemented as a noise canceller. The performance of the adaptive lattice will be analyzed and compared with that of an LMS transversal adaptive noise canceller. Experimental results will also be presented and discussed.
