基于DDS的BOC(m,n)信号发生器及其FPGA实现

BOC(m,n) Signal Generator Based on DDS and Its FPGA Implementation

介绍了BOC调制的特点和BOC(m,n)信号的产生方式;阐述了直接数字频率合成技术(DDS)原理,并将其应用在BOC(m,n)信号的产生过程当中;在此基础上,以BOC(1,1)信号为例,提出了该信号的一种产生方式,并以FPGA作为开发平台对其进行了实现。实验结果验证了本文方法的可行性。

The characteristic of the BOC modulation and the mode for generating BOC（rn,n） signal are presented. The principle of the DDS technology is described and used in the generation of BOC（rn,n） signal. Then, a method for generating BOC（m,n） signal is proposed with an example o[ BOC（1, l） and implemented on the FPGA development bench. Experimental result shows the feasibility of the method.
