For telemetry communication of hypersonic vehicles, the parasitic modulation effect caused by high-dynamic plasma sheath (PS) deteriorates communication quality. In this study, an adaptive noncoherent bit-interleaved coded modulation with iterative decoding (BICM-ID) system with the binary orthogonal-division dual-carrier modulation (BODM) under the hypersonic vehicle's <inline-formula> <tex-math notation="LaTeX">2\times M </tex-math></inline-formula> multi-in-multi-out (MIMO) telemetry channel is proposed. The key contributions of this study are that the proposed coding BODM-based BICM-ID system can adaptively realize the joint optimization of signal detection and decoding, throughout which the BODM is adopted to cope with the parasitic modulation effect of the PS channel and the soft information of BICM-ID is well estimated by reversible jump Markov chain Monte Carlo (RJ-MCMC) algorithms. Simulation results suggest that the proposed BODM-based BICM-ID system can well adapt to the dynamics and nonstationarity of the telemetry channel, exhibiting at least 8-dB performance improvement at bit error rate (BER) = 10 −6 compared with the BODM system.
