Paper Abstract
Continuous Phase Modulation (CPM) schemes are advantageous for low-power radios. The constant envelope transmit
signal is more efficient for both linear and non-linear amplifier architectures. A standard, coherent CPM receiver can
take advantage of modulation memory and is more complex than a coherent Phase Shift Keyed receiver. But the CPM
signal can be demodulated non-coherently and still take advantage of the trellis structure inherent in the modulation.
With this complexity reduction, the CPM receiver is comparable in performance to a Phase Shift Keyed radio with the
power utilization of a Frequency Shift-Keyed design. In this paper, we discuss two methods for increasing the
modulation memory of the CPM signal. In the first method, the distribution of the transmitted symbol across multiple
phase pulses is investigated and the bit error rate analyzed. In the next method we address the addition of convolutioncodes.
In both cases the effects of the CPM memory to quasi-coherent demodulation is analyzed and discussed. The
differences in complexity will be analyzed and the overall performance enhancements of several different modulation
schemes will be illustrated.
