摘要

高容量数字微波无线电设备的出现为PCM传输提供了一个有吸引力的替代方案。一个90 Mb/s的数字无线电在这里描述，它使用8 PSK调制，低损耗滤波，和现代固态设计，以实现高系统增益。还包括该无线电在滤波到2.26比特/赫兹时的性能，以及需要非常重的滤波才能达到3比特/赫兹时的性能。

A High Capacity Digital Transmission System at 11 GHz

The advent of high capacity digita1 microwave radio equipment is providing an attractive alternative for PCM transmission. A 90 Mb/s digital radio is described here which uses 8 PSK modu1ation, low loss filtering, and modern solid-state design to achieve a high system gain. A1so inc1uded is the performance of this radio when fi1tered to 2.26 bits/Hz and the performance with very heavy fi1tering needed to achieve 3 bits/Hz.
