Patent number: 8488439Abstract: A blind carrier frequency offset estimator is based on a single-OFDM-symbol training sequence in multi-user OFDMA uplink. Through multiple access interference modeling and analysis, a virtual user is employed that occupies the all null sub-carriers. By minimizing the energy leakage on the virtual user in term of tentative frequency offsets, the estimator can approach the real frequency offset. The estimator performs only on frequency-domain, simplifies interference calculations, and lowers the rank of the matrix. An iterative computation method is used to approach the real frequency offset.Type: GrantFiled: May 25, 2010Date of Patent: July 16, 2013Assignee: STMicroelectronics (Beijing) R&D Company Ltd.Inventors: Yiqun Ge, Xutao Zhou, Wuxian Shi
