Abstract

This paper, deals with channel estimation for UTRA-TDD. Based on the algorithm suggested by the 3GPP for scalar channels, a maximum likelihood (ML) approach for vectorial channel estimation, to include also the estimation of the direction-of-arrival, is proposed. The performance of the algorithm is assessed by resorting to simulations in typical UMTS scenarios, and also by comparing the RMS estimation errors against the Cramer-Rao bound. The results show that good performance is achievable from low to high values of E/sub b//N/sub 0/, provided the path components are separated by more than 2 chips.

UTRA-TDD模式的矢量多径信道估计

本文主要研究了UTRA-TDD的信道估计问题。在3GPP提出的标量信道估计算法的基础上，提出了一种包含到达方向估计的矢量信道估计的最大似然(ML)方法。通过在典型的UMTS场景中进行模拟，并将RMS估计误差与Cramer-Rao界进行比较，评估了算法的性能。结果表明，只要路径元件之间相隔2个以上芯片，从低到高的E/sub / b//N/sub 0/值都可以获得良好的性能。
