This invention provides channel dispersion estimation algorithm(s). This channel dispersion estimation algorithm(s) may be implemented within a channel length estimation module of a single-branch or multi-branch equalizer processing module that enables interference cancellation when the channel length or channel delay spread associated with received radio frequency (RF) bursts compares unfavorably to predetermined thresholds. The channel dispersion estimation algorithm identifies when the radio frequency (RF) bursts have a channel length or channel delay spread that can affect receiver performance. The channel length estimation module may disable interference cancellation in response to such a channel length or channel delay spread. Additionally, the channel length estimation module may adjust the number of equalizer states for the single-branch or first branch of a multi-branch equalizer based the channel length or channel delay spread. The multi-branch equalizer improves the signal-to-noise ratio by improving the equalization by selectively disabling interference cancellation and adjusting the number of equalizer states for the single-branch or first branch equalizer.
