ABSTRACT:
Viterbi decoding is implemented using an asymmetrical trellis70having an A-trellis72and a B-trellis74. The trellis70is designed for efficient implementation on a processing device40with arithmetic units42having multi-field arithmetic and logic capabilities By concurrently processing multiple path metrics in separate fields, a highly efficient decoder may be implemented in a software-controlled device.
