Abstract
Disclosed herein is a system and a method for estimating frequency offset of LTE using DMRS and CRC. The system includes one or more modules as follows. A digital filtering and FFT unitperforms FFT operation on a base band signal. An individual user data extraction unitextracts user data individual. A frequency correction unitprocesses the extracted user data if individual. A DEMAP into PUSCH and DMRS unitsplits a corrected frequency signal. An equalizer unitperforms channel equalization. The channel estimation unitdetermines a channel estimation (H). A multiplexer unitreceives the estimated frequency. An equalized data processing and CRC calculating unitreceives and processed the equalized data. A CRC value checking unitdetermines whether a calculated cyclic redundancy check (CRC) value is valid or invalid.
