摘　　要：随着卫星通信的迅猛发展,快速、有效地进行数据传输已经成为卫星通信的一个重要的发展方向。文中基于Matlab仿真验证,提出了一种卫星调制器分带滤波实现高速数据传输的新方法。与传统的方法相比,这种方法可以极大地减小A/D、D/A器件的采样率,从而降低了成本,提高了系统的可实现性。With the swift development of satellite communication,to transmit data fast and efficiently has been an important direction of satellite communication.After the validating of Matlab simulation,a new method of achieving high-rate data transmission was put forward,which is based on satellite modem banddivision filtering.Compared with the traditional methods,it can not only greatly reduce the sample-rate of A/D and D/A,but also cut down the cost and enhance the systematic realization.
