摘要
随着移动互联网和物联网的发展,人们对短距离通信无线个人局域网络的需求呈现爆炸式增长,为提高传输效率,改善边缘用户通信质量,并抵抗多径衰落,开展了能量缓存传输协议研究,分析了缓存辅助中继的协作分集方案不适合实际通信场景的具体原因,提出了基于瞬时信道状态信息进行链路选择的无线电能传输方法,通过信道估计来进行链路选择,能够明显减小误码率,增加3 dB以上的增益,同时也更符合各种环境复杂的通信场景。
With the development of mobile internet and Internet of Things,the demand for wireless personal area network and wireless body area network for short distance communication will increase explosively.In order to improve transmission efficiency,communication quality of edge users and resist multipath fading,energy buffer transmission protocol was studied,and the cooperative diversity scheme of cache assisted relay was analyzed,which was not suitable for practice for the specific reasons of communication scenarios.A wireless energy carrying transmission method was proposed based on instantaneous channel state information to select links,which could significantly reduce the bit error rate and increase the gain of more than 3dB.At the same time,it was more in line with the actual situation of various complex environment communication scenarios.
