A method and an apparatus are provided for improving a communication rate, which are used in a terminal working in a multiple-input multiple-output (MIMO) state. The method includes: obtaining strength of a first signal received in a first path connected to a first antenna and strength of a second signal received in a second path connected to a second antenna; and adjusting the first path or/and the second path according to a difference between the strength of the first signal and the strength of the second signal, so as to reduce an unbalance degree between the first path and the second path, thereby improving the communication rate. By adopting the present invention, improvement of a rate of an antenna may be achieved by adjusting a balance between the first and second paths.
