The prior art is available at 00103078.pdf . The technology overview The convolution performs a FIR filtering in digital signal processing. The advantage is that there is no input-output delay in the system. The disadvantage is that the input-output delay is twice the length of the filter. The input-output delay can be decreased by segmenting the filter and convolving the segments separately.
Prior art describes the case where segments are of the same size.
The patent describes the case where segments are of the same size but also the case where segments are unequal sizes. The software is now taken away from distribution, but I feel the case will progress only if the software is made available again. I would like to have somebody to read those prior art papers and verify my observations . U.S patent is also used for blocking the prior art algorithms. It should be noted that the patent seems to cover any application area, including those prior art applications.
