Estimation of Direction of Arrival and Delay Profile of Multipath Waves by MUSIC Algorithm for Indoor Radio Communication 多径波的到达方向和传播延迟时间的推定方法&用于室内无线电通信的MUSIC法
The main attention was concentrated to analysis of amplitude, waveform and arrival time delay of PPP and PPS twice-reflected phases, and to analysis of their relations with epicentre distance, velocity contrast on both sides of boundary, structures of the boundary and absorption of the medium. 文中集中分析了PPP和PPS型二次波震相的振幅、波形和到时差等特征,及其与震中距、界面两侧波速差、界面结构和介质吸收等因素的关系。
In multipath propagation model, arrival angle, delay and strength received by an antenna array for same signal source are estimated. 利用天线阵列对同一信源信号经过多径传输到达终端的时间时延、角度和强度进行了联合估计。
Through simulation, the estimation angle of arrival, departure angle and delay are achieved. 接着对SAGE算法做了归纳,在多径情况下,通过仿真实现离开角度、到达角和延时的估计。
The experiment results show that the proposed C-MUR can improve the packet arrival rate effectively with a delay constraint. 实验表明:C-MUR策略在满足一定的时延要求的条件下,有效地提高数据包到达率。
