Parametric design of an adaptive line enhancer for multiple switching tones in a correlated noise environment
… to a Lattice Filter can be used as an Adaptive Line Enhancer for sampled data consisting of multiple switching tones in correlated noise. A tradeoff analysis is performed with four methods of digital filtering including a conventional Digital Fourier Transform (DFT) algorithm, a Least …

Development Towards the use of Beamforming and Adaptive Line Enhancers for Audio Detection of Quadcopters
… of a home made quadcopter. A low cost uniform linear microphone array is first used to perform a simple delay-and-sum beamformer to spatially filter out noise sources. The beamformer output is then divided into sub-bands using three bandpass filters centered on the expected location of the …
