摘要
Systems and methods for providing a weighted overlap and add (WOLA) architecture and/or for providing polyphase WOLA FFT processing that may be employed, for example, for separation or channelization of closely-spaced frequencies of an input signal. A WOLA architecture that may be implemented as first-in-first-out (FIFO) cores in an FPGA or ASIC device. The FIFO cores may be pre-existing (e.g., provided as free FIFO cores in a commercial off the shelf (COTS) FPGA device) or may be custom-programmed into a custom ASIC device.
