An integrated circuit includes a reconfigurable FIR filter has an input port for receiving digital input signals and an output coupled to a coherent signal processor and a coherent memory. The FIR filter programmably provides filtered signals to the coherent signal processor for storage in the coherent memory. The integrated circuit further includes a sequential weight processor having an input coupled to an output of the coherent memory. The sequential weight processor includes a weight memory and operates to output symbol soft decision data resulting from processing the digital input signals. The integrated circuit is programmable into one of a plurality of operating modes, including at least one of a received signal acquisition mode, a channel estimator mode, an adaptive equalizer mode, and a channel-wise differential mode.
