A -- POST-DOCTORAL RESEARCH SOL F33600-95-R-0154. DUE 060595. Contact Point, Jerry A. Blais, Contract Negotiator, (513)257-8344, or J. S. Smith, Contracting Officer, (513)257-8344. The United States Air Force has the intent to award a contract for advanced, post-doctoral research work in the area of variable-length signal processing at the Air Force Institute of Technology (AFIT), School of Engineering, Department of Electrical and Computer Engineering. The awardee shall perform investigations into the foundations of variable length signal processing in the context of fourier and wavelet analysis, such as multidimensional non separable Malvar wavelets on arbitrary grids for applications to image and video data processing, Malvar wavelets and their connections with time-varying filter bank theory multirate filter bank lattice structures, multidimensional nonseparable discrete wavelet transforms, perfect reconstruction nonuniform sampling filter banks: necessary and sufficient conditions, factorizations and design, multidimensional multirate filter banks with perfect reconstruction property: necessary and sufficient conditions, factorizations and design. The awardee shall also perform research toward development of algorithms to achieve advances in flexible signal detection and discrimination schemes for application to problems in areas such as speaker identification and anti-jamming, such as, signal models using Malvar wavelets, time-varying filter banks, signal reconstructions using wavelet models: sampling, interpolations, extrapolations and moment problems, adaptive multirate filter banks in random processes with applications in speech. The awardee shall prepare two technical reports--an interim report, approximately at the chronological midpoint of research, containing preliminary results, and a final report published as an AFIT technical report. The awardee shall present final research results to AFIT faculty at a one-hour seminar at the conclusion of the period of performance. The quality of research conducted shall be sufficient for publications in an appropriate archival, refereed professional journal. The expected period of performance is a basic year with one option year. The solicitation will be issued approximately 05 May 1995. An Ombudsman has been appointed to hear concerns from offerors or potential offerors during the proposal development phase of this acquisition. The only purpose of the Ombudsman is to receive and communicate serious concerns from potential offerors when an offeror prefers not to use proposal development phase of this acquisition. Potential offerors should use established channels to request information, pose questions, and voice concerns before resorting to use of the Ombudsman located in ASC/CY, Bldg 2041, 2511 L St.. Serious concerns only. Direct all requests for solicitations and routine communication concerning this acquisition to the buyer listed elsewhere in this synopsis. All responsible sources may submit proposals which shall be considered. No telephone requests. Only written or faxed requests received directly from the requester are acceptable.
