基于ESPRIT的OFDMA系统初始测距方法

An ESPRIT-based approach for Initial Ranging in OFDMA systems

Luca Sanguinetti, Michele Morelli, H. Vincent Poor

摘要:

本文提出了一种新的正交频分多址网络初始测距方案。打算与基站(BS)建立通信链路的用户通常在时间和频率上都不对准,并且目标是联合估计它们相对于BS本地参考的定时误差和载波频率偏移。这是通过诉诸ESPRIT算法以可承受的复杂性来完成的。计算机模拟被用来评估所提出的解决方案的有效性,并与现有的替代品进行比较。

英文摘要:

This work presents a novel Initial Ranging scheme for orthogonal frequency-division multiple-access networks. Users that intend to establish a communication link with the base station (BS) are normally misaligned both in time and frequency and the goal is to jointly estimate their timing errors and carrier frequency offsets with respect to the BS local references. This is accomplished with affordable complexity by resorting to the ESPRIT algorithm. Computer simulations are used to assess the effectiveness of the proposed solution and to make comparisons with existing alternatives.
