Geometric microphone array calibration by multidimensional scaling

Classical multidimensional scaling is a simple, linear technique for finding coordinates of points given their interpoint distances. In this paper we describe the algorithm and show how it can be used to solve the geometric microphone array calibration problem. The method requires no complicated hardware or calibration targets, just a tape measure (or similar measuring device). We also extend t...

Investigation of coding structure in DNA - Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03). 2003 IEEE International

We have all heard the term "cracking the genomic code", but is DNA a code in the information theoretic sense? The coined term "genetic code" maps nucleotide triplets (codons) to amino acids. However, this is in computer coding sense because a codon instruction is performed to output an amino acid sequence. In this paper, we examine methods to detect redundant coding structure in DNA. First, a f...

A new approach for near-field wideband synthetic aperture beamforming

A coarray-based synthetic aperture beamformer using stepped-frequency signal synthesis and post-data acquisition processing is presented for wideband imaging of near-field scenes. The proposed beamformer formulation and implementation finds key applications in through-the-wall microwave imaging and landmine detection problems. While coarray techniques offer significant reduction in array elemen...
