3GPP LongTerm Evolution (LTE) is targeted towards variable transmission bandwidths to improve universal mobile telecommunications. This requires support for variable point FFT/IFFT (128 through 4096). ASIC solutions, one for a particular FFT is not cost-effective, while DSP solutions are not performance-effective. We hence provide a solution on REDEFINE, a dynamically reconfigurable platform, by appropriately characterizing the compute elements. We make use of the idle resources of REDEFINE to improve throughput by supporting multiple channels of FFT/IFFT.
