| 摘 要： | 提出了一种在ＦＨ／ＤＳ系统中以ＤＤＳ技术为核心，结合直接式技术构成混合快跳频频率合成器的设计方法。讨论了该方案的理论基础、跳频点分布及实际应用中截短ＲＯＭ地址，增大相位量化单位的可行性，并就由此引起的信噪比衰减和对多址工作的影响提出了解决方法。 |
| 关 键 词： | 快跳频 数字频率合成器 相位测量 截短 |

| Abstract: | In this paper, a method using direct digital synthesis (DDS) combined with mixing technique for implementing quick frequency hopping synthesizer in FH/DS system is presented.The basic theories of DDS and rational distribution of FH points are introduced and the feasibility of truncation of ROM address scheme for practice is discussed.The design problems,such as major parameters selections,singnal to noise ratio degradation and multi address degradation are all concerned in the paper. |
| Keywords: | Quick frequency hopping DDS Hybrid synthesizer Truncation Phase quantization |
