摘要
在宽带数字接收机中信道化是一个极其重要的环节。采用多相滤波器实现信道化是一种很好的方法,但现有的算法在信道间不是存在盲区就是存在混叠,本文的算法可以解决上述问题,并用MATLAB进行了仿真。仿真结果表明此方法有效可行。
Multi-channel plays a very important role in the design of a broad-band receiver. It is a good method that implements multi-channel by multi-phase filter. But those existing arithmetics have many defects , such as blind-zone or overlap. The arithmetic introduced in this paper can settle these problems. And emulator is performed by MATLAB. The result indicates that this method is feasible.
