摘要
提出了基于多输入多输出(MIMO)结构的新一代对流层散射通信系统框架。针对对流层散射系统电平微弱、多径传输和衰落严重,采用了空时编码(STC)、正交频分复用(OFDM)、单载波频域均衡(SC-FDE)等新技术,可使散射通信的信息速率在不增加带宽和发射功率的条件下获得1个数量级的提升。
The model of the new generation troposphere scatter communication system with multiple-input multiple-output is presented. Space time coding, orthogonal frequency division multiplexing and single carrier frequency domain equalization are used to solve weak signal, multi-path delivery and fast fading. As a result, the transmission rate can be improved greatly without widening the bandwidth or increasing the power.
