SYSTEM AND METHOD FOR FREQUENCY OFFSET ESTIMATION FOR SIGNALS CONTAINING MULTI-USER SYMBOLS

摘要

Systems and methods for frequency offset estimation are provided. A channel impulse response and multi-user signal parameter are jointly estimated. Based on the multi-user signal parameter, a determination is made as to whether the signal contains a single-user signal or a multi-user signal. Then, frequency offset estimation is performed based on this determination. For example, noiseless sample estimates are generated depending on whether the signal is a single-user signal or a multi-user signal.
