发明名称 Spread spectrum QAM transmission
摘要 <p>For each data element (symbol), a sequence of N points from a QAM constellation is transmitted. If the symbol period is T, then, in one embodiment, each point in the sequence has 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.</p>
