Low power architecture of the soft-output Viterbi algorithm
CT This paper investigates the low power implementation issues of the soft-output Viterbi algorithm (SOVA), a building block for turbo codes. By briefly explaining the theory of turbo codes, and by reviewing several of the decoding algorithms, we develop the computational requirements for a SOVA implementation, and ultimately develop an architecture that completes those computations with reduced power consumption. The architecture builds on previous work on the Viterbi and Soft-Output Viterbi algorithms, and incorporates a novel orthogonal access memory structure, which provides parallel access across sequentially received data.
