Abstract
En 中文
In this paper, we propose novel serial concatenated irregular convolutional-coded (IRCC) irregular precoded linear dispersion codes (IR-PLDCs), which are capable of operating near the multiple-input-multiple output (MIMO) channel's capacity. The irregular structure facilitates the proposed system's near-capacity operation across a wide range of SNRs, while maintaining a vanishing bit error ratio (BER). Each coding block of the proposed scheme and all the iterative decoding parameters are designed with near-capacity operation in mind, using extrinsic information transfer charts. By applying the irregular design principle to both the inner and outer codes, the proposed IRCC-aided IR-PLDC scheme becomes capable of operating as close as 0.9 dB to the MIMO channel's capacity for SNRs in excess of a certain threshold.
