This paper proposes a novel design framework, EXIT-constrained Binary Switching Algorithm (EBSA), for achieving near Shannon limit performance with Single parity check and Irregular repetition coded Bit Interleaved Coded Modulation and Iterative Detection with Extended Mapping (SI-BICM-ID-EM). EBSA is composed of node degree allocation optimization using Linear Programming (LP) and labeling optimization based on adaptive binary switching algorithm jointly. This technique achieves exact matching between the Demapper (Dem) and decoder's EXtrinsic Information Transfer (EXIT) curves while the convergence tunnel opens until the desired Mutual Information (MI) point.
