摘要：

High-rate low-density parity-check (LDPC) codes may be needed to ensure their transmission speed and reliability of high-speed communication systems and storage systems. Long and low-rate random LDPC code can achieve an excellent performance near Shannon limit. However, a high-rate random code with good error correcting performance is difficult to obtain. Structured LDPC codes are well known for the low error floor and low complexity. Therefore, high-rate structured LDPC codes with low error floor and more options of code length and rate are considered in this paper. Also, the BER performance of several LDPC codes is evaluated by simulation. In addition, the undesired error pattern of LDPC codes in the error floor region is analyzed from the numerical and simulation results.
