Abstract: A method of processing data based on programmed instructions includes referencing a number of locations in memory by forming addresses and correct buffer mappings corresponding to separate buffers in the plurality of buffers, and communicating data from the referenced locations in memory to a processing unit. The processing unit concurrently receives inputs from the separate buffers in the plurality of buffers and outputs to another buffer in the plurality of buffers.

Abstract: A buffering apparatus to process digital communication signals includes a plurality of buffers, a processing unit, and programmed memory. The programmed memory has instructions directing the processing unit to process the digital samples corresponding to a group of symbols to be processed in a plurality of buffers. The digital samples start in a first buffer of the plurality of buffers and end in a second buffer of the plurality of buffers. The digital samples are received at a third buffer of the plurality of buffers during the processing of the digital samples.

Abstract: A method of searching digital communication signals in a system includes combining a plurality of channel measurements, providing output of the combining of channel measurements as an added input to the plurality of channel measurements, and acquiring a signal symbol based on results from the combining of channel measurements without addressing all timing hypothesis individually via a correlation operation.
