JOINT SOURCE-CHANNEL CODING FOR MULTI-CARRIER MODULATION

摘要

Methods and systems employing combined source-channel coding for multi-carrier modulation (MCM) (502). In some embodiments, a described method coprises: estimating channel gain to noise ratio (CGNR) as a function of frequency bin (510); determining MCM parameters that minimize distortion of one or more telemetry signals; generating a communications signal using the MCM parameters, and transmitting the communications signal via a communications channel (504). The MCM parameters may be determined by minimizing a telemetry signal distortion measure subject to CGNR and a transmit power constraint (514). The MCM parameters may further account for differing fidelity requirements when multiple telemetry signals are being transmitted (S(t)).
