  Abstract

In this paper, carrier frequency offset and 2-D AoA (Angle-of-Arrival) estimation methods are proposed for an OFDM-based MRS (Mobile Relay Station) with UCA (Uniform Circular Array). The proposed methods are performed by using the preamble symbol in downlink and can improve the performance of CFO estimation significantly, compared with the conventional method. The proposed methods can be divided into two methods (method 1 and method 2) depending on the order of the AoA estimation and CFO estimation. It is shown by computer simulation under Mobile WiMAX environments that the proposed methods can estimate the CFOs and AoAs of adjacent BSs effectively.
