This paper discusses high-performance code construction and high-speed encoder and decoder designs for low density parity check (LDPC) codes. Thanks to their nice structures, LDPC codes constructed from shifted identity matrices have been emphasized. Several techniques in code constructions have been proposed to lower the bit error floor down to 10-10. Characterized by a parity check matrix in a triangular plus dual-diagonal form, these structured LDPC codes can be encoded in linear time using a layered encoding algorithm. To increase the throughput of decoders, a joint row-column decoding algorithm has been proposed and parallel decoding architectures have been used. The implementation results into field programmable gate array (FPGA) devices indicate that the encoder for these high-performance LDPC codes attains a throughput of up to 115 Gbits/sec and the decoder attains a throughput of up to 1 Gbits/sec. The proposed codes are suitable for high-speed and high-performance applications which demand relatively low error floor, including application in broadband wireless networks.
