1. A method for computing intersymbol interference-based estimates for a channel using reduced-state detection techniques, said channel having a channel impulse response, said method comprising the steps of: selecting a partial intersymbol interference-based estimate from among previously computed partial intersymbol interference-based estimates for path extensions into a state; and computing a plurality of new partial intersymbol interference based estimates, wherein at least one new partial intersymbol interference-based estimate is based on said selected partial intersymbol interference-based estimate, wherein said new partial intersymbol interference-based estimates are one or more of a partial intersymbol interference estimate and a partial intersymbol interference-free signal estimate and wherein one or more of said previously computed partial intersymbol interference-based estimates and said selected partial intersymbol interference-based estimates are stored in one or more of a pipeline register and a memory.
