Abstract:
In order to obtain the good error correction performance and the simple hardware implementation of low density parity check(LDPC)codes simultaneously,a construction method of parity check matrix of LDPC codes from shortened Reed-Solomon(RS)codes is proposed.On the basis of the constraints of regular LDPC codes and the features of shortened RS codes,the method is discussed focusing on the selection of the shortened RS codes parameters and partitions of coset.Taking the specific regular LDPC codes as a example,the construction process is introduced completely.The simulation results show that the method has the good error correction performance,can construct LDPC codes with different code length,columns and row weights by selecting the parameters of q,γ and ρ,and is a convenient algebraic construction method for the hardware implementation.
