Not Available Xenotran proposes to design for the Army a Turbo codec from VHDL. This codec will implement this novel algorithm using the latest published coredecoder architectures. It will be designed for implementation in VHDL andsynthesis to an FPGA. Xenotran proposes specifically to 1) Build a working software simulation environment for Turbo Code applications, 2) Develop Turbo codec VHSIC Hardware Description Language (VHDL) code and integrate its simulation into the simulation environment, 3) Project the performance of the VHDL Turbo codec as it would be if implemented in a variety of commercial FPGAs. These performance measures will include: 1) the possible speed of the codec given the underlying technology, 2) the circuit capacity (FPGA logic blocks or VLSI size) required by the Turbo codec, 3) the Eb/N0 versus BER capabilities of the device, 4) the data latency of the encoder and decoder, 5) the synchronization circuit performance, and 6) the bursty error behavior. For comparison, results will be benchmarked against commercially available Viterbi codecs. BENEFIT: Turbo codec technology IS useful in a wide variety or communications applications including satellite communications, cellular voiceband communcations, and wireless data networking in military and commercial systems. A system of the nature described in this proposal will have a substantial market encompassing all branches of the military and the commercial market.
