摘　　要：为了解决宽带数字通信系统多信道同时接收问题,这里针对宽带无线数字通信接收技术展开了深入研究,在研究信号采样理论的基础上,推导并给出了一种适用于宽带无线数字通信接收系统的多通道信道化高效模型。该模型利用原型滤波器的设计,在保证了滤波性能的同时获得了较少的阶数,降低了资源占有率,计算机仿真验证了该模型的正确性。该模型和传统模型相比有较少的计算量,适合于工程化应用。The wireless receiving technology for wideband digital communication is studied in this paper to solve the prob- lem existing in multi-channel receiving system for the wideband digital communication. The multi-channel efficient model suitable for wireless receiving system for wideband digital communication is derived and given through the study of signal sam- pling theory. The model gets fewer orders of filter by the design of prototype filter with same filtering performance and re- duces the resource occupation ratio of the system. The correctness of the model was verified by computer simulation. The model has less calculated amount, compared with traditional models, and is suitable for the engineering application.
