Abstract
Linear code linear programming (LCLP) proposed by Feldman is one of the promising methods to implement the lossy source coding process efficiently. In the encoding and decoding of a lossy source code constructed by sparse matrices, we propose auxiliary methods to obtain approximate optimal values in the case where the output of LCLP takes non-integer values. In a simulation, the proposed method attains smaller average distortions than the time-sharing bound.
