AbstractIn this paper, we propose multi-h CPM-SC-FDMA, a novel transmission scheme which combines many of the key characteristics of continuous phase modulation (CPM) with single carrier Frequency Division Multiple Access (SC-FDMA) to produce a power efficient, robust modulation which is suitable for high-rate multiple-access aeronautical telemetry applications. The basis of our approach is found in the observation that the discrete-time samples from a CPM waveform constitute a constant envelope time domain sequence which can be pre-coded and subsequently mapped to a set of orthogonal subcarriers for an FDMA-style transmission. The resulting waveform exhibits power efficiency and easily supports multiple access.
