The embodiment of the invention discloses a precoding processing method and device. The precoding processing method comprises the steps of: selecting a precoding processing method of each sub-band orsub-carrier according to a pre-set strategy, wherein the precoding processing method comprises linear precoding and nonlinear precoding; respectively performing precoding processing on data signals carried on each sub-band or sub-carrier by using the selected precoding processing method; and sending after mixing the precoded data signals carried on each sub-band or sub-carrier. According to the scheme provided in the embodiment of the invention, the precoding processing method can be selected; advantages of different precoding processing methods are sufficiently utilized; and thus, the systemperformance is improved. 本发明实施例公开了种预编码处理方法及装置。该预编码处理方法包括：根据预设策略选择各子频段或子载波的预编码处理方法，所述预编码处理方法包括线性预编码和非线性预编码；使用所选择的预编码处理方法分别对各子频段或子载波上承载的数据信号进行预编码处理；将各子频段或子载波上承载的预编码处理后的数据信号进行混合后发送。本发明实施例提供的方案，可以选择预编码处理方法，充分利用不同预编码处理方法的优势，提高系统性能。
