Protograph LDPC code design for LS-MIMO 1-bit ADC systems
Research works have proposed 1-bit ADC as a good candidate for LS-MIMO systems in order to save both transmission power and circuit energy dissipation. However, we observed that previously reported P-LDPC codes might not have good performance for LS-MIMO systems with 1-bit ADC. Hence, we perform a re-design of the P-LDPC codes for the above systems in this paper. The new codes demonstrate a good coding gain from 0.3 dB at rate 1/2 to 0.5 dB at rate 2/3 in different LS-MIMO configurations with 1-
