多通道全频点并行接收技术研究

Research on Multi-Channel Full-Frequency Parallel Receiver

多通道并行接收适用于对大带宽信号的采集处理,针对大带宽高速跳频通信系统射频频率切换时间短、大射频带宽采集成本高等问题,提出了一种多通道全频点并行接收系统设计思路,提出了一种基于两级变频的多通道信号下变频处理方案。所提系统对频率切换响应时间要求小,工程实现难度低。

For high-bandwidth and high-speed frequency hopping communication system,how to achieve real-time frequency switching and wideband sampling in low cost is still a challenging problem.Multi-channel parallel receiver is a good solution for wideband signal sampling.A new multi-channel full-frequency parallel receiving system is proposed.A new two-stage down frequency algorithm is proposed.The new proposal has low performance requirement for hardware devices.It is also simple for engineering implementation.
