Novel Multiplier-Optimised Real-Time Radix-4 IFFT Architecture for High-Throughput, Low-Latency Optical OFDM Transceivers on FPGA

Hermitian symmetry constrained optical OFDM in IM/DD transmitters incurs higher computational costs per transmitted bit than conventional complex-valued OFDM, as only a small subset of the IFFT subcarriers carry independent information. This work introduces a unified optimisation framework that combines juxtaposed IFFT...
