| Abstract: | The main principles of multithreshold decoding (MTD) are generalized to nonbinary codes. The lower bounds of the probability of erroneous decoding are proposed. The nonbinary MTD efficiency is shown to be close to the values attained via optimum search methods that cannot usually be implemented for nonbinary codes. The complexity of the implementation of the proposed decoders is discussed. |
