摘　　要：BOC(Binary Offset Carrier)信号是卫星导航中一种新的信号体制,对其中频信号模拟是验证基带处理算法的重要基础。针对BOC信号相关函数具有多个峰值特点,中频信号模型考虑了对相关峰值有影响的因素,并综合了信号从卫星到接收机传播中的多普勒效应、多径效应和噪声,以及接收机的处理等过程,以模块化结构进行了实现,并给出其中的运行结果。BOC（Binary Offset Carrier）signal is a new system in satellite navigation,simulation for its intermediate frequency（IF） is the base for verifying the baseband processing methods.Since the correlation function of the BOC signal has multiple peaks,the signal model takes the factors that affect correlation function peak values into account.The factors,such as Doppler effect,multi-path effect,the noise in signal transmission and process in receiver and so on,are also included.The IF signal is implemented in a modular way,and simulation results are shown in the end.
