提出了一种“广义多相滤波”的概念，将多相滤波推广至多相分解的阶数与抽取比不一致的情形，从而使得传统多相滤波成为其一个特例。“广义多相滤波”使得设计者在构建宽带数字接收机时可以按照实际情况进行速度与面积的平衡。从频域对广义多相滤波进行了推导，并给出了其具体实施步骤。在广义多相滤波的基础上，构建了一个宽带数字接收机，详述了该算法在其中的应用。还使用测试信号对该宽带数字接收机的功能进行了仿真，并给出了广义多相滤波在实际硬件中所使用的资源。结果表明，该算法对宽带数字接收机的研制有一定的实际意义。

A concept of generalized polyphase filtering(GPF)which extends the polyphase filtering to the case that the order of the polyphase decomposing is not the same as the decimation rate is presented in the paper,then,the conventional polyphase filtering becomes a special case of the GPF.The GPF makes it feasi-ble to balance the speed and the area as the practical situation in designing a wideband digital receiver.The authors deduce the GPF within frequency domain in the paper and the detailed approaches of the GPF are presented.A wideband digital receiver based on the GPF is presented and the application of the GPF in the receiver is described.The receiver is simulated by using a testing signal and the resource usage of the GPF in a practical device is educed by the simulation.It is indicated that the GPF has some practical advantages in the developing of the wideband digital receiver.
