宽带多通道微波收发信机的本振源设计应用分析

An Analysis of Design and Application of Local Oscillator for Broadband Multichannel Microwave Transceiver

在现代宽带数据用户不断提高的过程中,移动通信用户也在不断的发展,如何在一定频谱资源中使网络容量得到提高,并且提高网络覆盖性能,是现代网络建设过程中需要重点考虑的问题。要想能够在有限频谱资源中快速传输综合业务内容,就要具有较高频谱效率技术。MIMO-OFDM技术能够使无线系统容量得到提高,从而实现高速无线多媒体通信。未来宽带无线通信系统对于射频系统提出了较高的要求,所以就要设计稳定本振源。

With the continuous improvement of modern broadband data users,mobile communication users are also constantly developing.How to improve the network capacity and network coverage performance in a certain spectrum resource?It is a key problem to be considered in the process of modern network construction.In order to transmit the integrated service content quickly in the limited spectrum resources,it is necessary to have a high spectrum efficiency technology.MIMO-OFDM technology can improve the capacity of wireless system,so as to achieve high-speed wireless multimedia communications.The future broadband wireless communication system has posed the higher request to the radio frequency system,therefore we must design the stable local oscillator source.
