JOINT SOURCE-CHANNEL CODING FOR MULTI-CARRIER MODULATION

摘要

Methods and systems employing combined source-channel coding for multi-carriermodulation (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 moretelemetry signals; generating a communications signal using the MCMparameters, and transmitting the communications signal via a communicationschannel (504). The MCM parameters may be determined by minimizing a telemetrysignal distortion measure subject to CGNR and a transmit power constraint(514). The MCM parameters may further account for differing fidelityrequirements when multiple telemetry signals are being transmitted (S(t)).
