Abstract: This paper analyzes the measured broadband signal echoes modulated by digital coding metasurfaces (DCMs) and concludes that the non-ideal broadband modulation results are related to the ...
Abstract: In this letter, we propose a multilevel coded modulation (MLCM) scheme based on single parity check (SPC)-aided spatially coupled low-density parity-check (SC-LDPC) codes to enhance spectral ...
