Abstract

New ETSI and ITU regulations prescribe more stringent-rules for spectrum allocation in microwave frequency bands used for digital radio relay equipment. This implies usage of frequency-efficient modulation methods for data transmission. This paper deals with realization of intermediate frequency QPSK modulator employed in the RRU 13A digital microwave radio-relay link manufactured by Institute IMTEL.

用于IMTEL rru13a无线电中继链路的QPSK调制器

新的ETSI和国际电联规则对用于数字无线电中继设备的微波频段的频谱分配规定了更严格的规则。这意味着使用频率有效的调制方法进行数据传输。本文研究了中频QPSK调制器在IMTEL公司生产的RRU 13A数字微波中继链路上的实现。
