摘要
文章首先分析了DQPSK调制技术理论基础和直接射频调制发射系统体系结构。然后,针对工程实践,解决了窄带直接射频调制发射系统设计过程中出现的技术难点。文中提出的结论对直接射频调制发射系统的设计有一定指导意义。
In this paper, the theory of DQPSK and the architecture of DQPSK transmitter system are first analyzed. Then,a method to solve the technical difficulties in the realization of the narrowband DQPSK transmitter system is proposed. This results presented in this paper is useful for the realization of the DQPSK transmitter system.
