Abstract
Fractional rate modulation is accomplished by separating incoming data into frames of bits. Each frame is partitioned into bit words of unequal lengths. The words are divided by a modulus to obtain remainders. The remainders are transmitted using for example QAM modulation. At the receiving end the process is reversed. The ratio of the baud rate of the system to the incoming bit rate defines the modulus as well as the number of QAM modulation points.
