摘　　要：建立多信道软件无线电接收机数学模型,介绍了ADI公司的高性能宽带多载波数字中频接收芯片AD6654电路结构和主要特性。在此基础上提出一种数字中频在cdma2000多载波接收系统的设计及应用方案,并给出了系统各个单元的设计和性能参数,最后仿真验证了方案的可行性。Established the mathematic model of multi-channels SDR receiver. The paper also introduced the circuit configuration and mostly character of AD6654,whieh is a high-powered broad band mutiearrier digital IF receiver chip produced by ADI. Based on these, it introduced a scheme about the application of digital IF in edma2000 multiearrier receiver system. And it also presented the design and parameter of every unit in the system. At last, feasibility of the scheme is validated by simulation.
