Near-Capacity Irregular Precoded Linear Dispersion Codes

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 (R) 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 near-capacity 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 p = -7dB.
