Abstract
Disclosed is a method of providing signal processing operations, including convolution/filtering, where each parallel stream is processing signals at a lower rate than the signal data rate itself while still resulting in an overall signal processing rate suitable for high rate signal processing. This allows devices with a lower signal processing rate to be used in the parallel processing paths, avoiding many of the problems facing prior art high data rate signal processing. The invention converts a signal from the time domain to the frequency domain and takes advantage of associative and communicative properties of data processing to perform signal processing operations in parallel.
