From LDPC Codes to LDA Lattices : A Capacity Result

This paper contains a summary of the arguments used to show how to achieve capacity of the AWGN channel with Voronoi constellations of LDA lattices under lattice decoding. No dithering is required in the tranmission scheme and capacity is achievable with LDA lattices whose parity-check matrices have constant row and column degrees. Although most of the… CONTINUE READING
