一种结合符号速率的带通采样速率选取方法

Selection of Pass-band Filter Rate in Consideration of Symbol Rate

带通采样速率选取是软件无线电中最为关键的问题之一，本文首先分析了常用的带通采样速率选取方法的不足之处，然后提出了一种实用的带通采样速率选取方法，最后通过MATLAB仿真证明了该方法的正确性和可行性。

The selection of pass-band sampling rate is one of the key problems to the design ot sort- ware radio. This paper analyses the disadvantage of usual way to select the sampling rate, and put forth a practical way for the selection. Finally the correction and feasibility have been proved by MATLAB simulation.
