摘要

介绍了一种柔性数字多频时分多址调制器的实现和测试。调制器能够在突发的基础上在几个频率(跳频)下工作，没有前奏或保护时间。在简要回顾了一些卫星概念(例如，MF-TDMA，板载处理器和通信效率)之后，介绍了直接带内调制作为该跳频调制器数字设计所选择的技术。采用混合Si/GaAs技术进行硬件实现，并进行了测试，证明了器件的良好性能。

A flexible digital multicarrier modulator for multi-frequency TDMA satellite transmission

The implementation and test of a flexible digital multi-frequency time division multiple access (MF-TDMA) modulator are presented. The modulator is able to work at several frequencies (frequency hopping) on a burst basis without preambles or guardtimes. After a brief review of some satellite concepts (e.g., MF-TDMA, onboard processor, and traffic efficiency), direct-in-band modulation is introduced as the technique selected for the digital design of this frequency hopping modulator. A mixed Si/GaAs technology has been chosen for the hardware implementation and some tests are presented to show the good performance of the device.<>
