In this paper, a Direction-of-Arrival (DoA) estimation scheme with cell searching is proposed for a mobile relay station (MRS) with uniform circular array (UCA) at handover region. The proposed scheme of cell searching and DoA estimation for the MRS with UCA is robust even when there exist symbol timing offsets (STOs). Compared with the previous scheme, the proposed scheme can reduce computational complexity and processing time for cell searching and DoA estimation. Simulation results are included to verify the performance of the proposed scheme under Mobile WiMAX environment.

    ABSTRACT: Relaying and cooperation have re-emerged as important research topics in wireless communication over the past half-decade. Although multihop relaying for coverage extension in wireless networks is an old concept, it became practical only recently. Nowhere is this better illustrated than in the IEEE 802.16 working group, which has devoted a task group to incorporating relay capabilities in the foundation of mobile WiMAX-IEEE 802.16e-2005. Currently, this task group is in the process of finishing IEEE 802.16j, the multihop relay specification for 802.16. This amendment will be fully compatible with 802.16e-2005 mobile and subscriber stations, but a BS specific to 802.16j will be required for relays to operate. This article presents an introduction to the upcoming IEEE 802.16j amendment and provides insight about the obstacles that practical system designers face when incorporating relaying into a wireless broadband network.

    ABSTRACT: The problem of 2D angle estimation (azimuth and elevation) of multiple plane waves incident on a uniform circular array (UCA) of antennas is considered. Two eigenstructure-based estimation algorithms that operate in beamspace and employ phase mode excitation-based beamformers have been developed. The first, UCA-RB-MUSIC, is a beamspace version of MUSIC that offers numerous advantages over element space operation, including reduced computation, as subspace estimates are obtained via real-valued eigendecompositions, enhanced performance in correlated source scenarios due to the attendant forward-backward averaging effect, and the applicability of Root-MUSIC. The second, UCA-ESPRIT, represents a significant advance in the area of 2D angle estimation. It is a novel closed-form algorithm that provides automatically paired source azimuth and elevation estimates. With UCA-ESPRIT, the eigenvalues of a matrix have the form μ<sub>i</sub>=sin θ<sub>i</sub>e<sup>jφ(i/), where θ</sup>sub i/ and φ<sub>i</sub> are the elevation and azimuth angles, respectively. Expensive search procedures being thus avoided, UCA-ESPRIT is superior to existing 2D angle estimation algorithms with respect to computational complexity. Finally, asymptotic expressions for the variances of the element space MUSIC and UCA-RB-MUSIC estimators for the 2D scenario have been derived. Results of simulations that compare UCA-RB-MUSIC and UCA-ESPRIT and also validate the theoretical performance expressions are presented

    ABSTRACT: This paper reviews and presents the latest results in the cell search issue of the 3GPP Long Term Evolution (LTE) systems. Cell Search is a basic function of any cellular system, during which process time and frequency synchronization between the mobile terminal and the network is achieved. Such synchronization is especially important for 3GPP Long Term Evolution systems, which rely heavily on the orthogonality of the uplink and downlink transmission and reception to optimize the radio link performance. As in conventional cellular systems, the mobile terminal in an LTE system acquires time and frequency synchronization by processing the synchronization channel. Design of the synchronization channel is being developed within the standardization activities of 3GPP Long Term Evolution and is still evolving. In this paper, we present the design considerations and various new and promising design concepts for the synchronization channel. We evaluate some specific solutions and provide numerical performance results.
