摘要
从中频带通采样理论出发,分析了采样频率的选取方法,重点研究了数字多通道接收机方案和数字下变频技术,并对各个模块进行了Matlab仿真和FPGA时序仿真加以验证,结果证明了方案的可行性和正确性,在工程应用中具有一定的参考价值。
Combined with the specific research, this paper analyzed the selection methods of sampling frequency based on IF band-pass sampling theorem. Focusing on the digital multi-channel receiver proposal and digital down-conversion technology, each module was verified by maflab simulation and FPGA timing simulation. The results demonstrate the feasibility and correctness of proposal, which has big reference meaning in the engineering application.
