Disclosed in the present invention are an antenna merge algorithm selection method and device, wherein the method comprises: obtaining a covariance matrix of interference noise on a data carrier; obtaining a maximum and a minimum eigenvalue of the covariance matrix; demining magnitude relationship between a preset threshold and condition data, wherein the condition number is the ratio of the maximum eigenvalue to the minimum eigenvalue; according to the comparing result, selecting a current used antenna merge algorithm of the data carrier. With the above technical solution of the present invention, provided is a solution to the problem in related art that there is no effective technical solution to realize adaptive selection of an appropriate algorithm from multiple antenna merge algorithms, fundamentally captures the effect proportion of the interference and noise to the receiving system, and then can be able to adaptively select the corresponding merge balance algorithm according to the proportion This selection method is robust, effective and improves the receiving performance of the system.
