Abstract: This presentation provides a summary of the results obtained from a study which evaluates the performance of variable coded modulations specified in the “Variable Coded Modulation Protocol” CCSDS Red Book, over a nonlinear channel that is currently on the CCSDS Blue Book track. The objectives are to perform simulation that identifies the operating signal-to-noise-power ratio required to achieve a codeword error rate of 1e-4 over the specified nonlinear channel for various modulations (i.e. BP…
