Abstract

一种终端设备、发射机、基带芯片以及射频信号生成方法，以在不增加生成射频信号的设备的成本以及功耗的前提下，降低CIM3对保护频带的干扰。该终端设备包括应用处理器、基带处理器、本振以及上变频器；其中，应用处理器用于触发基带处理器发送资源块RB信号；基带处理器用于确定RB信号的中心频点相对于零点的偏移量△f，以及控制本振将本振产生的本振信号的中心频点flo调整为flo+△f；本振用于在基带处理器的控制下，将本振产生的本振信号的中心频点flo调整为flo+△f；上变频器用于生成射频信号，其中，射频信号为上变频器利用中心频点调整后的本振信号对中心频点为零的RB信号进行上变频处理得到的。
