Submissions are invited for a special session on “Novel Techniques for Exploiting Convolutive Mixtures” to be held at the 16th International Conference on Digital Signal Processing (DSP2009) in Santorini, Greece, July 5-7, 2009. Over the last few years there has been a surge of interest in signal processing techniques for exploiting spacetime convolutive mixtures. Convolutive mixtures arise in a wide range of contexts from MIMO communication over frequency selective channels to broadband sensor array processing for sonar and radar, underwater acoustic communications and, of course, the classic “cocktail party problem”. Recent areas of interest include, for example, blind and semi-blind signal separation from convolutive mixtures, the exploitation of spatial and temporal diversity in MIMO wireless communications and space-time adaptive processing (STAP) for radar or sonar. To date, most of the signal processing for convolutive mixtures has been carried out by transforming the received signals into the frequency domain; the problem simplifies to one of scalar (instantaneous) mixing at each individual frequency. However, some recent research has been devoted to processing convolutive mixtures in the time domain with the mixing process represented by a polynomial matrix, i.e. a matrix of polynomials where each element represents an FIR filter. The signal processing is then carried out by exploiting some newly established techniques for polynomial matrix factorization such as the polynomial EVD and QRD algorithms. This special session is dedicated to fostering closer interactions amongst researchers developing and applying any state of the art technique for exploiting convolutive mixtures, It should provide an excellent opportunity to meet and discuss the rich variety of ideas in this specific area. Research papers are solicited on any relevant topic such as: Polynomial matrix factorization Frequency domain methods such as OFDM Blind and semi-blind convolutive signal separation Application to MIMO communications Application to broadband sensor arrays Application to space-time adaptive processing (STAP) Benchmarking and comparison of techniques All accepted papers will be published in the conference proceedings and will be available for online access via IEEE Xplore.
