Patent ID: 11063854

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 unit 106 performs FFT operation on a base band signal. An individual user data extraction unit 108 extracts user data individual. A frequency correction unit 110 processes the extracted user data if individual. A DEMAP into PUSCH and DMRS unit 112 splits a corrected frequency signal. An equalizer unit 114 performs channel equalization. The channel estimation unit 116 determines a channel estimation (H). A multiplexer unit 122 receives the estimated frequency. An equalized data processing and CRC calculating unit 124 receives and processed the equalized data. A CRC value checking unit 126 determines whether a calculated cyclic redundancy check (CRC) value is valid or invalid.
