1. A method for synchronize word correlation, comprising:
obtaining, by a correlator, first values that each indicate a likelihood or probability that a respective timeslot in a symbol timing window of a carrier wave is meant or expected to include energy;
multiplying, by the correlator, the first values respectively by correlation coefficients to produce a plurality of products, wherein at least one of the correlation coefficients comprises a negative coefficient value;
generating, by the correlator, a correlation value by combining the products together;
determining, by the correlation, whether a synchronization word has been detected with a given amount of likelihood based on the correlation value; and
causing, by the correlator, symbol timing synchronization at a receiver when a determination is made that the synchronization word has been detected with the given amount of likelihood based on the correlation value.
