Abstract
This paper presents fully parallel fast Fourier transform (FFT) processor for coherent optical OFDM system. It has a length of 256. For processing of 100 Gb/s throughput it has parallel input and output structure. FFT processor has 32 radix-16 processor with trivial multiplication and consists of an array structure in parallel arithmetic processing. We designed and implemented the proposed FFT processor using Xilinx FPGA XCVU190. The result shows 205,530 LUTs and the maximum throughput is 46.592 Giga-Samples/sec.
