SUMMARY

A receiver system for demodulating a high-entropy continuous phase modulation (HE-CPM) signal is disclosed in accordance with one or more illustrative embodiments of the present disclosure. In one illustrative embodiment, the system comprises a plurality of complex multipliers configured to receive the synchronized HE-CPM signal, wherein each of the complex multipliers removes a phase associated with a respective one of a plurality of inter-symbol interference (ISI) hypotheses and generates a respective one of a plurality of complex multiplier outputs, wherein each ISI hypothesis includes a previous chip hypothesis corresponding to a binary value for a previous chip, and a next chip hypothesis corresponding to a binary value for a next chip. In another illustrative embodiment, the system comprises a summer configured to combine real parts of the plurality of complex multiplier outputs to generate a soft decision for a current chip of the HE-CPM signal, wherein the soft decision is a demodulated output of the current chip of the HE-CPM signal.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not necessarily restrictive of the invention as claimed. The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and together with the general description, serve to explain the principles of the invention.
