ABSTRACT:
For each data element (symbol), a sequence of N points from a QAM constellation is transmitted. If the symbol period is T, then each point in the sequence may have a duration T/N. The sequence is determined by treating the constellation as a finite ring, and repeatedly multiplying the data point by a constant point.
