1. A method of hybrid channel estimation in a wireless communication receiver, comprising: receiving a wirelessly transmitted signal including a training sequence; performing a correlation channel estimate on the received signal to generate correlation based channel estimates; filtering the received signal based on the correlation based channel estimates to generate a filtered signal; assessing one or more noise metrics of the filtered signal; in response to a noise metric, optionally performing noise whitening filtering on the filtered signal; and performing a least squares based channel estimate on the filtered signal to generate final channel estimates.
