Description

The Naval Undersea Warfare Center, Division Newport intends to award a Firm Fixed Price Contract on a Sole Source basis to Northeastern University, Department of Electrical and Computer Engineering, 350 Huntington Ave., Boston, MA to develop the Underwater Range Data Communications (URDC) telemetry system. This includes developing and refining both the RAKE based direct sequence spread spectrum receiver and transmitter and the hypothesis feedback equalization based direct sequence spread spectrum receiver and transmitter; applying both of the spread spectrum algorithms to one or more simulated and real underwater channels as field tests permits in order to evaluate performance; analyzing and comparing the RAKE based system's overall performance to the overall performance of the hypothesis feedback equalization based system; incorporating turbo decoder into turbo equalizer transmitter and receiver and also modifying maximum A posteriori (MAP) probability decoder and soft output Viterbi algorithm to work on short blocks of equalized data to facilitate integral iterative processing; and delivering the documentation and Matlab code that details the theory of operation for the algorithms, their operation, and the development of design methodologies based on complexity, performance, and parameter sensitivity. The existing telemetry techniques have been used to provide full duplex communications between bottom-mounted transducers cabled to shore and transducers onboard submarines on range. This telemetry system will serve as a prototype for further development. Advancements in algorithm development are required for certain telemetry applications to be used by the Underwater Range and Data Communications (URDC) program at AUTEC. The Government plans to issue a request for written quote to Northeastern University using FAR Part 12 and FAR Part 13. The anticipated award date is 23 November 2001. This action is being processed on a sole source basis due to the fact the work requires the use of field tested and proven, proprietary algorithms and software to make the required modifications, refinements, and comparisons. The NAICS code for this requirement is 611310. All proposals from responsible sources will be considered. Telephone requests will not be honored.
