Abstract:
This research proposes a new method of decoding convolutional codes using
quantum computers. The proposed method obtains maximum likelihood (ML)
estimate of the transmitted codeword using quantum annealing (QA). The performance
of the proposed method is assessed by its error performance and compared
with the conventional Viterbi decoder on classical computers. The results verify
the feasibility of QA for decoding convolutional codes. Furthermore, the execution
time of both classical and quantum computers for decoding are compared and
discussed.
