Paper Abstract

In recent years, a number of techniques have been suggested that combine two or more repetitions of the same message to improve the efficiency and reliability of digital communications systems. This combining is performed so that the combined message can be decoded properly, even though the individual transmissions contain uncorrectable errors. Significant performance gains can be achieved when multiple repetitions of contaminated messages are combined. Although combining techniques previously have been analyzed for binary transmission schemes employing majority vote decision, calculation of the performance in the case of M-ary channels is more complex. This paper describes a methodology called plurality voting, and demonstrates the performance obtained when message combining is used on an M-ary channel with this decision rule.
