摘要

本文介绍了一种利用现成的可编程逻辑器件技术实现宽带GMSK编码器的低成本、低空间硬件实现。这种灵活的技术允许实现一个编码器，可以处理从几百Kbit/s到8 Mbit/s的输入数据，只需改变以下本地元素:低成本晶体振荡器和输出低通滤波器。第二部分介绍了一种尚未在硬件上实现的方法。提出了一种单纯使用简单数字技术对GMSK基带频谱进行正交调制的方法。

Efficient and simple hardware realization for broadband GMSK-modulators using PLD-technology to enable MPEG2-transmissions in a standard TV-channel

In this paper a cost- and space-reducing hardware realization of a broadband GMSK coder is described by using off-the-shelf PLD-technology. This flexible technology allows the realization of a coder that can process input datarates from a few hundred Kbit/s up to 8 Mbit/s by simply changing the following local elements: the low-cost crystal-oscillator and the output lowpass-filter. The second part of this paper describes a method which has not been realized in hardware yet. A quadrature modulation of the GMSK baseband spectrum by purely using simple digital techniques is presented.
