Wireless communication technology continues to advance at a rapid pace, and researchers have made tremendous progress in extending single-input single-output (SISO) systems to multiple-input multiple-output (MIMO) systems such as IEEE 802.11n, WiMAX, and LTE. However, a MIMO system requires a detector circuit to separate received data. To reduce the number of comparators required, the method of modified...
In this paper, we construct the cyclic block-type low-density parity-check (CB-LDPC) codes for low complexity hardware implementation. The CB-LDPC code, which is a special class of quasi-cyclic LDPC (QC-LDPC), has an efficient encoding algorithm due to the simple structure of their parity-check matrices. A distribution of irregular parity-check matrix for the CB-LDPC is developed so that we can obtain...
