摘要
在全面论述带通信号的采样定理,并对带通采样后的频谱结构仔细分析的基础上,从工程应用的角度出发,提出一种中频频率、采样频率联合优化的方法。将此方法应用于cdma2000多载波数字中频接收机的设计中,验证了它的可行性和实用性。
This paper discusses the sampling theory of bandpass signal, and analyses the configuration of frequency after sampling. Considering the engineering application, it proposes an associated method to achieve the optimal performance. It also applies the method to the design of cdma2000 multi - carrier digital IF receiver, which validates its feasibility and practicability.
