摘要

提出了一种基于电磁波波前空间信号处理的无线中继链路带宽容量改进方法。给出了一种单跳单工无线电中继链路实验室样机的测试结果，该样机在发射端和接收端都进行了空间信号处理。该原型机在8 MHz带宽下，以相同的10.56 GHz载波频率和相同的电磁波极化，以41.25 Mbps的比特率同时并行传输两个64-QAM调制的DVB-C无线电信号，距离为8米。该原型可用于研究应用空间信号处理技术提高无线电中继链路射频资源复用和带宽能力的可能性。

Application of Spatial Signal Processing for Bandwidth Capability Improvement of Radio Relay Link

Novel method of radio relay link bandwidth capacity improvement based on spatial signal processing by the wave front of the electromagnetic wave are presented. Test results of a variant of one-hop simplex radio relay link lab prototype with spatial signal processing both in the transmitting and receiving sites are shown. This prototype provides simultaneous parallel wireless transmission of two DVB-C radio signals with 64-QAM modulations at bit rates of 41.25 Mbps over 8 MHz bandwidth with the same carrier frequency of 10.56 GHz and with the same electromagnetic waves polarization at distance of 8 meters. This prototype can be used for research the possibility of radio frequency resource reuse and bandwidth capability improvement for radio relay links by applying spatial signal processing techniques.
