摘　　要：Three classes of structured regular Low- density parity-check （LDPC） codes with girth at least 6 are constructed from frequency-hopping sequences. The parity-check matrices of these codes have uniform row and column weights, simple and explicit structure, as well as a large variety of candidate parameters. Simulation resuits show that the new codes perform very similar to the randomly constructed LDPC codes over Additive white Gaussian noise （AWGN） channels.
