—In this treatise, we propose a novel serial concatenated RSC-coded Irregular Precoded Linear Dispersion Codes (IR-PLDC), which is capable of operating near MIMO channel’s capacity. The irregular structure combined with the employment of an Infinite Impulse Response (IIR) precoder facilities the proposed system’s operation across a wide range of SNRs, while maintaining an infinitesimally low BER. Each coding block of the IR-PLDC scheme is designed with nearcapacity operation in mind with the aid of Extrinsic Information Transfer (EXIT) charts. The proposed RSC-coded IR-PLDC scheme is capable of operating as close as 2.5dB to the MIMO channel’s capacity, namely at SNRs as low as ρ = −7dB.
