摘　　要：通过对射频接收机中的带通采样技术的研究,在最佳采样速率区间选取的基础上,结合采样精度需求、频带保护、用户器件性能的约束条件,逐步缩小了采样速率的选取区间,提出了一种简洁、有效的最佳带通采样速率求解方法。最后通过Simulink仿真,验证了该算法的可行性。Through the research of bandpass sampling RF receiver and based on selection theory of optimal sampling rate range,to combine constraint condition of precision demands,guard bands and device performance,gradually decrease the slection range of sampling rate,one brief and effictive solution of the optimal bandpass sampling rate is proposed.Finally its feasibility is verified by simulink simulation.
