The embodiment of the invention provides a pre-coding method, a base station and user equipment and relates to the field of communication. According to the invention, a nonlinear pre-coding scheme can be selected adaptively to improve the system performance. The pre-coding method comprises the following steps: the base station acquires predetermined parameters of at least one piece of user equipment; the acquired predetermined parameters are calculated to obtain a calculation performance index; a target pre-coding scheme is selected according to the calculation performance index; data information of all the user equipment is pre-coded according to the scheme; the base station transmits the data information and an indication signaling which indicates nonlinear pre-coding scheme information to all the user equipment if the target pre-coding scheme is a nonlinear pre-coding scheme; the user equipment receives the data information and the indication signaling which are transmitted by the base station; a receiver is selected based on a receiver type obtained according to the indication signaling; and the received data information is detected by using the selected receiver. The embodiment of the invention is used for pre-coding of an MIMO system.
