We present a general class of finite geometry LDPC codes which perform well with iterative decoding although their Tanner graphs may contain many cycles of length 4. A hybrid two-stage decoding algorithm is proposed that combines iterative and multi-step majority-logic decodings to achieve good performance with low decoding complexity.
