The invention relates to an uplink transmission method for resisting inter-carrier interference, a computer readable storage medium, a distributed multi-antenna system and a joint optimization methodfor a matrix coefficient of an inter-carrier interference self-elimination coding matrix and a degree distribution coefficient of rateless coding. The joint optimization method is applied to a distributed multi-antenna system adopting an orthogonal frequency division multiplexing technology under a block fading channel, and comprises the following steps of determining an optimization problem of jointly optimizing a matrix coefficient and a degree distribution coefficient by taking maximization of a system transmission rate as a target according to statistical information of a channel state andexternal information transfer analysis of a decoding process; and solving an optimization problem to obtain an optimized matrix coefficient and an optimized degree distribution coefficient. Through the application, the problem that the wireless transmission rate and the ICI elimination effect are difficult to consider due to the fact that the matrix coefficient of the ICI self-elimination codingmatrix and the degree distribution coefficient of rateless coding are independently optimized is solved, and the ICI elimination effect is improved on the basis that the wireless transmission rate isguaranteed.
