Low Density Parity Check Coding
Original language description
It is generally known that the code achieving Additive White Gaussian Noise (AWGN) channel capacity must have Gaussian distribution and infinite codeword dimension. In current communications such code is very frequently approximated by linear parity check code over finite field F^n_p having generating matrix that induces sparse parity check matrix with large dimension. This paper should summarize low density techniques used in channel code design. In the first part of this paper we focus on Low DensityParity Check (LDPC) codes properties over finite field and algorithms for generating matrices with desired properties. In the second part we describe Euclidean space extension known as Low Density Lattice Codes (LDLC), which can be efficiently used in dense networks by its natural structure.Recently, it was shown that lattice based codes can reach AWGN channel capacity, but under infinite codeword dimension constraint. This condition makes lattice codes practically unrealizable. However,
