摘　　要：为了提高传输效率,E波段微波传输系统采用了不加循环前缀的单载波块传输方式,针对多径信道中传输时引入的块间干扰,采用频域交叠均衡技术有效消除了前后数据块之间的混叠干扰。通过MATLAB仿真评估,该技术可以在中低信噪比时以较低的系统复杂度实现系统传输速率的提升以及多径效应的消除。To increase the bandwidth efficiency,the way of single-carrier block transmission without cyclic prefix is applied for E-band microwave transmission system.As to the emergent inter-block interference due to multiple channel,an extremely efficient overlap frequency-domain equalization scheme is proposed,which can cancel the aliasing interference among blocks significantly.Through MATLAB simulation,we can find this scheme can achieve the promotion of transmission rate and cancellation of multiple effect at the cost of very little system complexity,when the SNR is not high.
