摘　　要：针对精密测距和高速数传一体化信道的应用需求,首先给出了总体设计方案,即利用高级在轨系统(AOS)空间链路层协议提供的相关业务,采用双向转发式测距伪码。针对基带转发模式提出了三种具体的实现方案,经过详细的理论分析和仿真,全面地分析了各种方案的优缺点,并指出了各自的适用范围。New methods for designing an integrated channel are proposed in this paper for pseudo noise code ranging and high speed data transmission. The integrated design scheme is given which uses the services and protocols provided by advanced Orbiting System of CCSDS, and pseudo code ranging based on bidirectional forwarding method. Three implementation approach- es are proposed for base band forwarding mode. Through the detailed theoretical analysis and simulation, the advantages and dis- advantages of each approach are studied comprehensively and application range of each approach is put forward.
