摘要
以软件无线电思想为基础,采用非相干解扩解调、M元扩频等技术,提出了一种同时传输两个物理信道,实现快速同步捕获和高速信息传输的CDMA-VSAT收发信机的新设计方案。这种收发信机可用单片DSP和FPGA实现,结构简单、设计灵活、可扩展性强,为VSAT网中的一些高速业务的应用奠定了基础。
Based on the idea of software radio and the technique of non - coherent despreading/demodulation and M-ary spreading spectrum, a new scheme of CDMA-VSAT transceiver is presented, which can bring about faster synchronization acquisition and higher bit rate. It has a simple and flexible structure and can be easily realized with DSP and FPGA.
