Radio controlled clock (RCC) is a kind of time measuring technique that uses wireless radio to transmit time signals, purposing on synchronizing the signals of wireless receivers and solving the precision and synchronization problems of clocks between different ranges. This paper has thoroughly analyzed the transmitting characteristics and the encoding principle of RCC and based on the existing technique,...
In this paper, a modified WiMAX Low-Density Parity-Check (LDPC) codes for realistic LDPC coding system architectures is presented. The LDPC code, which is a special class of quasi-cyclic LDPC (QC-LDPC), has an efficient encoding algorithm owing to the simple structure of their parity-check matrices. A proposed distribution of irregular parity-check matrix for the modified WiMAX LDPC is developed so...
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...
