Methods and Systems for Determining an Optimal Training Interval in a Communications System. A method is provided for determining an optimal training interval for a channel of a communications system. The method can include a step for receiving first channel estimations of a signal carried by a channel of a communications system, wherein the first channel estimations are generated by a first channel estimator. The communications system can include a normal mode for utilizing the channel to carry user data, a training mode for training the first channel estimator, and a failure mode for recovering channel communication after channel failure. The method can include a step for determining a time distribution of the channel transition from the normal mode to the failure mode, wherein channel failure occurs when error in the first channel estimations exceeds a first predetermined threshold. Further, the method can include a step for applying Markovian analysis to the time distribution of the channel transition to determine a first training interval such that channel utilization in the normal mode is maximized.
