Methods, systems, and devices for wireless communications are described. Generally, the described techniques may enable a user equipment (UE) to use a frequency estimator (e.g., a maximum likelihood estimator) that may be based on a pilot signal sent over M distinct symbols. That is, the frequency estimator may be based on all available cross-correlations of pilot signals in a reference signal. In some examples, the frequency estimator may achieve an increased pull-in range and estimation performance based on weighting the available cross-correlations in accordance with the channel statistics. The described techniques may also support asymmetrical symbol spacings between pilot signals in one or more reference signals, which may further improve pull-in range of the frequency estimator. Additionally, or alternatively, aspects of the frequency estimator may be combined with aspects of another frequency estimator to increase the pull-in range with relatively low computation complexity at the UE.
