A construction technique is proposed for low-density parity check (LDPC) codes. It uses a base parity check matrix designed from a ran-dom or constructed construction method as Gallager or Quasi-Cyclic LDPC (QC-LDPC) codes in sequence to get codes with multiple lengths and same rate of the base matrix. This is done by using a seed matrix with row and column weights of one, distributed randomly and can be addressed by a number in the base matrix, this method reduces the mem-ory usage and reduce the probability of failing to construct a parity ma-trix by random approaches. Also, by the use of circulant identity seed matrices, QC-LDPC codes can be obtained keeping the same performance
